High energy consumption and automated production processes
are typical for many industries.
If you want to keep your energy costs under control in the
long term and you are already focusing on the digital future,
it's a good idea to equip your plant with integrated energy
measuring technology, thus anchoring energy management into
the automation of your production processes – which is where
most energy is consumed.
SIMATIC Energy Suite as an integrated option for the TIA Portal
efficiently links energy management with automation, thus
creating energy transparency in the production system.
The considerably simplified configuration of energy measuring

Take the SIRIUS 3SK safety relays for example: They are
modularly expandable, and can integrate compact motor
starters such as the fail-safe SIRIUS 3RM1 very simply via the
device connector (parameterization is performed easily with
a screwdriver on the DIP switches or by drag and drop in the
engineering software).
The SIMOCODE pro modular motor management system
combines all required protection, monitoring, safety and control
functions for motor feeders. It can be connected to fail-safe
controllers via PROFIBUS or PROFINET and shut down motors
in emergency situations.
SIRIUS Safety Integrated uses fail-safe communication via
standard fieldbus systems, such as ASIsafe via AS-Interface
and PROFIsafe via PROFIBUS and PROFINET, to solve even
networked safety tasks of greater complexity. This opens the
door to flexible safety solutions for compact machines or large-
scale plants – naturally compliant with current standards up to
SIL 3/PL e.
The first integrated ASIsafe connection to the distributed
I/O system ensures even more consistency. With the
SIMATIC AS-i F-Links, AS-i networks can be connected
quite simply to safety controls via PROFIsafe via the
SIMATIC ET 200SP.
Particular highlights are the 3RT contactors
of sizes S2 to S12 with fail-safe control input, the
SIRIUS ACT 3SU1 EMERGENCY STOP with PROFINET or
PROFIsafe interface, and the fail-safe motor starters for
ET 200SP (page 8/94 onwards) and the 3RW55 fail-safe soft

• For reliable operation of an AS-i network with 24 V voltage,

AS-Interface configuration with AS-i master modules in the ET 200SP

The AS-i communications modules in the ET 200SP
facilitate the use of AS-Interface under fail-safe SIMATIC
or SINUMERIK controllers.
The allocation of tasks is as follows:
• Acquisition of safety-related signals via safe input slaves on
the AS-Interface bus.
Further signals can be detected through other F-DI modules
of the SIMATIC.
• Evaluation and processing of signals via the fail-safe SIMATIC
or SINUMERIK control
• Reacting by means of safety output modules on the
AS-Interface bus
or other SIMATIC F-DQ modules
Simple combination of the CM AS-i Master ST and
F-CM AS-i Safety ST modules in one ET 200SP station results in
a powerful, safety-related network transition between PROFINET
(or PROFIBUS) and AS-Interface, which can be expanded
further in a modular fashion with further I/O modules of the
ET 200SP.
Using these design methods, it is possible to create
configurations for virtually any application. Besides the single
AS-i master, double, triple or generally multiple masters can be
realized with or without Failsafe functionality.

The following modules are available for selection:

K20F compact safety modules for use in the field

Being only 20 mm wide, the K20F module is particularly well
suited for applications where modules need to be arranged in
the most confined space. The K20F modules are connected to
the AS-Interface with a round cable with M12 cable box instead
of with the AS-Interface flat cable. This enables extremely
compact installation. The flexibility of the round cable means
that it can also be used on moving machine parts without any
problems. The K20 modules are also ideal for such applications
as their non-encapsulated design makes them particularly light
in weight.

■ Overview
AS-i gateways with ET 200SP
An AS-i gateway or AS-i link enables access to the AS-Interface

data via PROFINET or PROFIBUS.
With the CM AS-i Master ST module, flexible and powerful
PROFINET/AS-i links or PROFIBUS/AS-i link solutions are set up.
Depending on the requirements, even several AS-i masters can
be plugged into one ET 200SP station, so that the setup can
easily be extended from a single master to double masters or
multiple masters.
The maximum number of modules is determined by the
ET 200SP interface module (IM): Up to 8 AS-i masters with
PROFINET IM 155-6PN Standard, up to 43 AS-i masters with
IM 155-6PN High Feature, or a single AS-i master with
IM 155-6PN Basic. For the connection to PROFIBUS,
the IM 155-6DP HF interface module with up to 7 AS-i master
modules is used.
Since in many plants an ET 200SP station with I/O, motor starter
CM AS-i Master ST for SIMATIC ET 200SP or other peripheral modules is provided, the AS-i master
modules are simply plugged in without any additional effort.
There are countless possible combinations.
An AS-i Safety gateway can also be implemented without
any problems by adding the safety-related module

Diagnostics information is accessed via automatic alarm
indications, via the status information in the process image or
via the graphical status display in the online diagnostics of the
TIA Portal. The transmission quality of the AS-i network can also
be read out. To avoid configuration errors, duplicate addresses
can be detected on the AS-i network.
Configuration is possible with SIMATIC CPUs S7-300 up to
S7-1500 and with a SINUMERIK 840D sl or other controller.
The online diagnostic status of the AS-i slaves can be
displayed directly on the slaves in the network view in TIA Portal
(for S7-1500 CPUs with firmware version V 2.0 or higher).

Masters for SIMATIC S7 > CM 1243-2

■ Overview Function
The CM 1243-2 supports all specified functions of the
AS-Interface specification V3.0.
The values of the digital AS-i slaves can be activated via the

2
process image of the S7-1200. During configuration of the
slaves in the TIA Portal, the values of the analog AS-i slaves can
also be accessed directly in the process image.
If required, master calls can be performed with the data record
interface, e.g. read/write parameters, read/write configuration.
Changeover of the operating mode, automatic application of
the slave configuration and the re-addressing of a connected
AS-i slave can be implemented via the control panel of the
CM 1243-2 in the TIA Portal.
The optional DCM 1271 data decoupling module (see
"Accessories", page 2/38) has an integrated detection unit
for detecting ground faults on the AS-Interface cable.
The integrated overload protection also disconnects the
AS-Interface cable if the drive current required exceeds 4 A.

acquired at pin 4 while the signal for the inputs is acquired at
pin 4 and pin 2. As the result, sensors can be connected directly
to pin 2 and pin 4.
Y-assignment
With the Y-assignment, two sensors or two actuators can be
connected to one M12 socket. In this case, both pin 4 and pin 2
are provided for one sensor signal and one actuator signal on
each M12 socket.
K60
In this case, the second socket is not required and is closed with
a sealing cap.
Y-II assignment
The Y-II assignment offers the following options:
• Individual connection of a sensor/actuator to one M12 socket
• Connection of two sensors/actuators to one M12 socket
as follows:
- The signal of the first sensor/actuator is connected to pin 4
of the first socket.
- The signal of the second sensor/actuator is connected to
pin 2 of the first socket and to pin 4 of the second socket.

All compact modules are characterized by particularly
simple handling. The K60 and K45 modules are mounted with
a mounting plate. The mounting plate is used to mount the
AS-Interface flat cables and enables mounting on a wall
or DIN rail.
The particularly narrow K20 modules are directly mounted
without a mounting plate and connected to the AS-Interface
using a round cable.

■ Overview
Addressing and connection of the sensors/actuators
Addressing of the K60 modules is performed using an

addressing socket integrated in the compact module.
The addresses can also be assigned after installation.
K60 modules with a maximum of four digital inputs and outputs
These compact modules contain the M12 standard connections
for inputs and outputs. Using M12 standard plugs, a maximum
of four sensors and four actuators can be connected to the
compact module.
K60 compact modules with a maximum of eight digital inputs
These modules have eight digital inputs for connection through
M12 plugs.
The module requires two AS-Interface addresses for processing
all eight inputs. The addressing can thus be performed through
a double addressing socket integrated in the module.
K60
The K60 digital AS-Interface compact modules are K60 data couplers

Robotics is yet another application area. The K20 modules are
connected to the AS-Interface with a round cable with M12 cable
box instead of with the AS-Interface flat cable. The AS-Interface
2

bus cable and the 24 V DC auxiliary energy are routed in this

case in a shared round cable. This enables extremely compact
installation.
The flexibility of the round cable means that it can also be used
on moving machine parts without any problems. The K20
modules are also ideal for such applications as their non-
encapsulated design makes them particularly light in weight.
In applications with cable carriers, many users rely on placing
the AS-Interface bus cable in a round cable. In this case, the K20
modules support direct connection to the round cable. No flat to
round cable adapter is required.
The K20 compact module range includes standard AS-Interface
modules, as well as an ASIsafe version for the connection of
safety-related sensors, such as EMERGENCY STOP
Digital I/O modules, IP67 - K20 pushbuttons or protective door monitoring.
The K20 compact module series rounds off the AS-Interface For particularly space-saving dimensions, the sensors

I/O modules for use in the field, high degree of protection > Analog I/O modules, IP67 - K60

■ Overview ■ Benefits
• Analog modules are just as easy to integrate in AS-Interface
as digital modules
2

• Analog values can be easily detected and issued locally

• Preprocessing of the analog value transfer in the master
enables rapid evaluation of the analog values
• Up to four values can be detected using one analog module
• Faster transmission and conversion of analog values thanks to
the new option for switching to single-channel operation
In addition, specification V3.0 now also offers:
• A/B technology, now also with analog modules
• On average, double fast transmission times (only 3 or
4 cycles, depending on the resolution selected)
• Variable adjustable mode: 12-bit or 14-bit resolution,
1-channel or 2-channel, selectable via the ID1 code

K60 analog compact module

More information
Manual for AS-Interface analog modules, see
https://support.industry.siemens.com/cs/ww/en/view/7643815

AS-Interface analog modules from the K60 compact series

detect or issue analog signals locally. These modules are linked
to the higher-level controller through an AS-Interface master
according to specification V2.1 or specification V3.0.
The analog modules are divided into the following groups:
• Input modules for
- Current measurement
- Voltage measurement
- Thermal resistance measurement
• Output modules for
- Current actuators
- Voltage actuators
The input modules according to profile 7.3/7.4 are available with
two or four input channels. It is possible in addition to convert the
2-channel module to using only one input channel, thus enabling
very short times before the analog value is available. The
conversion is effected by means of a jumper plug at socket 3.
The transmission times achieved with analog modules
according to profile 7.A.9 are twice as fast as those achieved
with profile 7.3/7.4. Operation is adjustable in this case, e.g. it is
possible to choose with the ID1 code whether the module is
operated with 1 or 2 channels.
The output modules are configured as 2-channel modules
as standard.
The input and output channels are electrically separated
from the AS-Interface network. If sensors with a higher power
requirement are to be connected, more power can be supplied
through the auxiliary voltage as an alternative to the internal
supply.
In the manual (see "More information"), the modules are
presented in great detail along with their technical specifications
and in-depth notes on operation. Sample function blocks round
off the manual.

the existing SlimLine devices with SlimLine Compact devices.
Note:
The previous SlimLine devices are still available for use as
replacements in existing systems. As a result of the innovation,
the new SlimLine Compact devices are not fully compatible in
terms of either mechanical dimensions or electrical properties.

■ Overview
"Ground faults in any control circuit must not lead to unintentional
starting or potentially hazardous movements or prevent the
machine from stopping." (IEC 60204-1/VDE 0113-1).

2
The AS-Interface ground-fault detection module is used to meet
these requirements. Using this module from the SlimLine series,
ground faults in AS-Interface systems can be reliably detected
and reported.
The following ground faults are detected:
• Ground fault from AS-i "+" to ground
• Ground fault from AS-i "-" to ground
• Ground fault on sensors and actuators that are supplied from
the AS-Interface voltage.
Note:
Not suitable for AS-i Power24V.
Check whether the AS-i power supply unit or the AS-i master
module, etc. features integrated ground-fault detection, and
Ground-fault detection module with spring-loaded terminals therefore whether a separate ground fault detection module can

Modules with special functions > Overvoltage protection modules

■ Overview
With the AS-Interface overvoltage protection module, it is now
also possible to integrate AS-Interface in the overall overvoltage
protection concept of a plant or machine.
2

The module has the same design and degree of protection (IP67)
as the AS-Interface K45 compact modules. It is a passive module
and as such does not need its own address on the AS-Interface
network. The module can be used to protect the AS-Interface cable
and the cable for the auxiliary voltage from overvoltage.
Overvoltages are discharged through a ground cable with a green/
yellow oil-proof outer sheath. This cable is fixed in the module and
must be connected with low resistance to the system's ground.

AS-Interface shaped cable

■ Overview
To enable use in the most varied ambient conditions (e.g. in an
oily environment), the AS-Interface cable is available in different
materials (rubber, TPE, PUR).
2

For special applications it is also possible to use an unshielded

standard round cable H05VV-F 2 x 1.5 mm² according to
AS-i specification. With AS-Interface, data and energy for the
sensors (e.g. proximity switches) and actuators (e.g. indicator
lights) are transmitted over the yellow AS-Interface cable.
The black AS-Interface cable must be used for actuators with
a 24 V DC supply (e.g. solenoid valves) and a high power
requirement.
Suitable for operation in cable carriers
The use of the AS-Interface shaped cables with TPE and PUR
outer sheath was checked in a cable carrier test with the
following conditions:
Chain length m 6

• Electrical separation of the two AS-Interface shaped cable
lines, e.g. interfering signals or ground faults are blocked at
the repeater. The wanted signals are prepared by the repeater
and passed on after amplification.
• Slaves can be used on both sides of the repeater because the

Power contactors for switching motors
SIRIUS 3RT12 and 3TF6 vacuum contactors

■ Overview
If there are further switching elements in the circuit, such as the
auxiliary contact system of an overload relay that operates the
contactor, the short-circuit protection necessary for this must
also be considered.
For further recommendations, e.g. the use of miniature circuit
breakers or circuit breakers for equipment in control circuits, see
Control panel tip – Fast, reliable selection and dimensioning of

an appropriate power supply unit.

Protection of contactors with digital input from short circuit
and overload
For the PLC input types according to IEC 60947-4-1 these inputs
have a typical rated current of 20 mA.
These inputs can be protected accordingly (for 3RT12..-.N
contactors marked with IN+/IN-).
The supply voltage connections A1 - A2 must be protected
3RT12 and 3TF6 vacuum contactors according to the load characteristics.

Operating mechanism types
3RT12 vacuum contactors
The contactors can be operated with AC (50 to 60 Hz) as well as
with DC.
Two types of solenoid operation are available:
• Standard operating mechanism for AC and DC operation
(power consumption reduced from closing to closed),
version 3RT12..-.A
• Solid-state operating mechanism, version 3RT12..-.N
3TF6 vacuum contactors
• Standard version 3TF6.44-.C.7 with AC operation
• Version 3TF6.33-.Q.7 for AC control supply voltage subject to
strong interference:
Contactors in this version are more robust against
EMC interference and are therefore designed for operation in
systems with AC control supply voltage that is subject to
strong interference. A 3TC44 (3TY7684-0Q..) reversing
contactor with a series resistor fitted is used to switch over
to holding control. The reversing contactor can be mounted
separately. It is connected to the 3TF6 main contactor by
means of a pre-assembled connecting cable (approx. 1 m
long) with plug-in connectors.
This version is recommended in the environment of frequency
converters and in the case of unshielded control cables.
• 3TF6.33-.D.4 contactors with DC control are supplied with
a 3TC4417-4A.. reversing contactor and a series resistor.

reversing, provided they are interlocked by way of their
auxiliary switches (NC contact interlock) and the mechanical
interlock.
For assemblies with AC operation and 50/60 Hz, a dead
interval of 50 ms must be provided when used with voltages
over 500 V; a dead interval of 30 ms is recommended for use
with voltages up to and including 400 V. These dead times do
not apply to assemblies with DC operation.
The operating times of the individual contactors are not
affected by the mechanical interlock.
• Mechanical interlocks

Additional components
• For momentary-contact operation: auxiliary switch
(NO contact) for self-locking
• 3RB2 overload relays (see page 7/114 onwards),
SIMOCODE pro 3UF7 motor management and control
devices (see page 10/12 onwards) or 3RN2 thermistor motor
protection relays (see page 10/136 onwards) can be used for
overload protection.
The overload relay can either be mounted on the line
contactor or separately fitted. It must be set to 0.58 times
the rated motor current.
• Optional surge suppression for the S3 contactors; the
contactors in sizes S6 to S12 are wired as standard with
varistors.
The contactor assemblies for star-delta (wye-delta) starting
for customer assembly are designed for standard applications.
Note:
Contactor assemblies for star-delta (wye-delta) starting in
special applications such as very heavy starting1) or star-delta
(wye-delta) starting of special motors must be customized.
Help with designing such special applications is available from
our Technical Support,
www.siemens.com/support-request.

1)
For effective assistance from Technical Support, you must provide the
following details:
- Rated motor voltage,
- Rated motor current,
- Service factor, operating values
- Motor starting current factor
- Starting time
- Ambient temperature

■ Overview
Protection against overvoltage at the control supply voltage
connection
3RT23 contactors supplied without a coil circuit can be
retrofitted with RC elements, varistors, diodes or diode
assemblies (combination of diode and Zener diode for short
break times) for damping switching overvoltages in the coil and
can be ordered separately as accessories, see page 3/97
onwards.
3RT13 contactors are already equipped with coil damping
(varistor).
Note:

4
The break times of the contactor, the opening delay times of the
NO contacts and the closing delay times of the NC contacts
increase with damping.

must be taken into account, for example for cable dimensioning. Equipment Manual.
One possible protection for these circuits could be the selection
of a suitable power supply, i.e. one with a current-limiting
function. In the selection of the source and the connecting cable,
the load characteristics of the contactor must be considered
(short-time inrush current peaks for solid-state operating
mechanisms, switch-on power, holding power).
If there are further switching elements in the circuit, such as the
auxiliary contact system of an overload relay that operates the
contactor, the short-circuit protection necessary for this must
also be considered.
For further recommendations, e.g. the use of miniature circuit
breakers or circuit breakers for equipment in control circuits, see

must be considered depending on the type of connection: marked with IN+/IN-). The supply voltage connections A1 - A2 must
be protected based on the load characteristics.

see the technical product data sheet.
Protection against overvoltage at the control supply voltage
For more information on complete units such as contactors with connection
overload relays or contactors with motor starter protectors as the
motor feeder, see Configuration Manual for load feeders. 3RT contactors are already equipped with coil damping
(varistor).
Note:
The break times of the contactor, the opening delay times of the
NO contacts and the closing delay times of the NC contacts
increase with damping.
For more information about influencing the time response using
damping, see Equipment Manual.

must be taken into account, for example for cable dimensioning.
One possible protection for these circuits could be the selection
of a suitable power supply, i.e. one with a current-limiting
function. In the selection of the source and the connecting cable,
the load characteristics of the contactor relay must be
considered (short-time inrush current peaks for solid-state
operating mechanisms, switch-on power, holding power).

3RQ coupling relays: Spring-loaded terminals (push-in) with

TOP wiring
Push-in terminals are a form of spring-loaded terminals allowing
fast wiring without tools for rigid conductors or conductors
equipped with end sleeves.
As with other spring-type terminals, a screwdriver (with
3.0 x 0.5 mm blade) is required to disconnect the conductor.
The same tool can also be used to wire finely-stranded or
stranded conductors with no end finishing.
The advantages of the push-in terminals are found, as with all
spring-loaded terminals, in speed of assembly and disassembly
and vibration-proof connection. There is no need for the
checking and tightening required with screw terminals.
With the TOP wiring method, the wire inlet and terminals can be
reached from the front. This helps to speed up the wiring
process and eliminate wiring errors.

Further fields of application are based on the force-guided
operation of relays according to IEC 60947-5-1 and EN 61810-3
for reading back relay states, for reliable diagnostics or signaling,
or for the use of antivalent signals. Typical fields of application
here are railways, signaling technology and elevators.
The series consists of devices with up to five outputs and can be
supplied with screw or spring-loaded (push-in) terminals.
International standards and certifications including CE, UL/CSA,
EAC and railway approvals ensure international usability and
exportability.

3RQ2 coupling relays in their 22.5 mm industrial enclosure serve
to couple control signals to and from a controller and replace
the 3RS18 coupling relays. The 3RQ2 has an impressively
high-quality industrial enclosure finished in modern titanium
gray so that it fits in visually with the SIRIUS series of relays.
The series consists of devices with up to three changeover
contacts with screw or spring-loaded terminals (push-in) and,
with its wide voltage range from 24 to 240 V AC/DC, is a genuine
highlight in the coupling relay market.

■ Benefits
General Coupling relays with relay output (not plug-in)
• All versions with screw terminals or spring-loaded terminals • Relays fixed in enclosure for increased contact reliability
(push-in technology) • Device variants with hard gold-plated contacts, hence high
• TOP wiring with spring-loaded terminals (push-in) for quick contact reliability at low currents
and reliable wiring
Coupling relays with plug-in relays
• Low space requirements in the control cabinet thanks to a
consistent width of 6.2 mm • Fast replacement of the relays with existing wiring
• Reduced stock-keeping due to fewer variants • Shorter installation times thanks to certified complete units
• Clearly visible functional state of the coupling relay by green • Individual relays available as spare parts
LED • Device variants with hard gold-plated contacts, hence high
• Integrated reverse polarity protection and EMC suppressor contact reliability at low currents
diode Coupling relays with semiconductor output (not plug-in)
• Standardized accessories across the entire 3RQ3 series • Long service life since there is no mechanical wear
• Universal bridging option using connecting combs for all • High switching frequency thanks to short make-break times

5
terminals
• Vibration-resistant
• Galvanic isolation plate for isolating different voltages for
neighboring units • No contact bounce
• Clip-on labels available as set for individual labeling • Extremely high contact reliability
• Noise-free switching
• Low control power required
• Switching of DC and capacitive loads
Note:
With semiconductors, the switching current is not dependent
on the inductance of the load, i.e. the switching current for an
inductive DC-13 load is the same as that for a DC-12 load.
This means that coupling links with a semiconductor output are
particularly suitable for inductive loads such as solenoid valves.
It is not relevant to specify the number of operating cycles,
because this does not affect the endurance of the semiconductor,
provided it is not overheated.

■ Application
• Electrical separation between the input and output circuit
• Adjustment of different signal levels
• Signal amplification

LZS coupling relays with plug-in relays can be ordered as Protective separation
complete units or as individual modules for customer assembly. For protective separation, transfer of the voltage of one circuit to
another circuit is prevented to a suitable degree of safety
Function
(requirements and tests are described in IEC 60947-1 in Annex N).

consumption and are therefore particularly well-suited to solid- Notes on the previous LZX series

accordingly in both the LZS and the LZX series.

Control with solid-state output
Note:
In the case of solid-state outputs (e.g. proximity switch) with
overload and short-circuit protection, you must make allowance Due to differences in geometry, the LED modules, plug-in

a suitable LZS coupling relay with plug-in relay. The LZS series offers not only service-proven screw connections
but also versions with plug-in terminals (push-in).
Surge suppression
The 24 V DC relays LZX:RT and LZX:PT with LEDs can be
supplied with, all others without integral surge suppression
(freewheeling diode connected in parallel with A1/A2). The
positive control supply voltage must be connected to coil
terminal A1.
Mounting
The relays are plugged into the base and this is snapped onto
a TH 35 DIN rail according to IEC 60715.
A fixing bracket can be ordered for the MT series that
additionally fixes the relay into a plug-in socket (under
conditions of increased mechanical stress). For the RT and
PT series, a combined fixing and ejection bracket is available
which can be used to disassemble the relays when they are
mounted side-by-side.
They can be mounted as required.

Note:
Logical separation: The terminals for the contacts and the
terminals for the coil are arranged on separate levels, e.g. above
for contacts and below for the coil. Logical separation is not
necessarily protective separation.
Protective separation: Protective separation prevents voltage
of one circuit affecting another circuit with sufficient protection
(IEC 61140).

Note:
The service factor and measurement inaccuracies, for example,
have been taken into account for the selection of the specified
motor starter protectors/circuit breakers; the specified short-
circuit breaking capacities Iq in kA are covered by combination
tests. Smaller motor starter protectors/circuit breakers from the
same series can be used at any time as smaller ones trip more
quickly in the event of a short circuit (unchanged short-circuit
breaking capacity) and thus protect the soft starter in any case.
The dimensioning of the short-circuit components must match
the connected three-phase motor, the short-circuit and overload
requirements of the application, and the line protection for the
cables used.
When using braking functions, the use of fuses is recommended
to avoid the risk of false tripping of 3VA circuit breakers with
electronic motor protection function during braking.
In motor feeder tests with soft starters conducted in 690 V
systems, demonstrable short-circuit breaking capacities could
only be achieved using fuses (Iq > 5 to 10 kA).

Note:
The specified short-circuit breaking capacities Iq in kA are
covered by combination tests. Smaller fuses than those
specified can be used at any time as smaller ones trip more
quickly in the event of a short circuit (unchanged short-circuit
breaking capacity) and thus protect the soft starter in any case.
The dimensioning of the short-circuit components must,
however, be suitable for the connected three-phase motor
and the line protection for the cables used.
In inside-delta circuits, motor feeders with soft starters can only
be operated in systems with up to 600 V.

Note:
The specified short-circuit breaking capacities Iq in kA are
covered by combination tests. Smaller fuses than those
specified can be used at any time as smaller ones trip more
quickly in the event of a short circuit (unchanged short-circuit
breaking capacity) and thus protect the soft starter in any case.
The dimensioning of the short-circuit components must,
however, be suitable for the connected three-phase motor
and the line protection for the cables used.
In inside-delta circuits, a gR/gS class full-range fuse could not
provide the semiconductor protection of the delta-connected
soft starter with a short-circuit breaking capacity that is
adequate for practical use. In this case, we recommend using
aR class partial-range fuses for semiconductor protection for
type of coordination "2" (see page 6/27).

For CLASS 10 applications, as an alternative to the 3NA3
gG class full-range fuses for cable and line protection (F1),
3RV2 motor starter protectors/3VA circuit breakers can also be
used, possibly with reduced short-circuit breaking capacity (see
page 6/24). In these cases, optional line contactors can be
dispensed with.

Note:
The service factor and measurement inaccuracies, for example,
have been taken into account for the selection of the specified
motor starter protectors/circuit breakers; the specified short-
circuit breaking capacities Iq in kA are covered by combination
tests. Smaller motor starter protectors/circuit breakers from the
same series can be used at any time as smaller ones trip more
quickly in the event of a short circuit (unchanged short-circuit
breaking capacity) and thus protect the soft starter in any case.
The dimensioning of the short-circuit components must match
the connected three-phase motor, the short-circuit and overload
requirements of the application, and the line protection for the
cables used.

The dimensioning of the short-circuit components must,

In inside-delta circuits, a gR/gS class full-range fuse could not
provide the semiconductor protection of the delta-connected
soft starter with a short-circuit breaking capacity that is
adequate for practical use. In this case, we recommend using
aR class partial-range fuses for semiconductor protection for
type of coordination "2" (see page 6/49).

For CLASS 10 applications, as an alternative to the gG class
full-range fuses for cable and line protection 3NA3 (F1), 3RV2
motor starter protectors/3VA circuit breakers can also be used,
possibly with reduced short-circuit breaking capacity
(see page 6/46). In these cases, optional line contactors
can be dispensed with.

Note:
The service factor and measurement inaccuracies, for example,
have been taken into account for the selection of the specified
motor starter protectors/circuit breakers; the specified short-
circuit breaking capacities Iq in kA are covered by combination
tests. Smaller motor starter protectors/circuit breakers from the
same series can be used at any time as smaller ones trip more
quickly in the event of a short circuit (unchanged short-circuit
breaking capacity) and thus protect the soft starter in any case.
The dimensioning of the short-circuit components must match
the connected three-phase motor, the short-circuit and overload
requirements of the application, and the line protection for the
cables used.

The dimensioning of the short-circuit components must,

In inside-delta circuits, a gR/gS class full-range fuse could not
provide the semiconductor protection of the delta-connected
soft starter with a short-circuit breaking capacity that is
adequate for practical use. In this case, we recommend using
aR class partial-range fuses for semiconductor protection for
type of coordination "2" (see page 6/66).

Note:
The specified short-circuit breaking capacities Iq in kA are
covered by combination tests. Smaller fuses than those
specified can be used at any time as smaller ones trip more
quickly in the event of a short circuit (unchanged short-circuit
breaking capacity) and thus protect the soft starter in any case.
The dimensioning of the short-circuit components must,
however, be suitable for the connected three-phase motor
and the line protection for the cables used.
For CLASS 10 applications, as an alternative to the gG class
full-range fuses for cable and line protection 3NA3 (F1), 3RV2
motor starter protectors/3VA circuit breakers can also be used,
possibly with reduced short-circuit breaking capacity

Note:
The service factor and measurement inaccuracies, for example,
have been taken into account for the selection of the specified
motor starter protectors/circuit breakers; the specified short-
circuit breaking capacities Iq in kA are covered by combination
tests. Smaller motor starter protectors/circuit breakers from the
same series can be used at any time as smaller ones trip more
quickly in the event of a short circuit (unchanged short-circuit
breaking capacity) and thus protect the soft starter in any case.
The dimensioning of the short-circuit components must match
the connected three-phase motor, the short-circuit and overload
requirements of the application, and the line protection for the
cables used.

Industry Mall, see www.siemens.com/product?3RW40 www.siemens.com/tstcloud/?node=3rw40

Conversion tool, see www.siemens.com/conversion-tool

The SIRIUS 3RW40 Basic Performance soft starters are suitable

for soft starting and stopping of three-phase asynchronous
motors.
Thanks to 2-phase control, not only is the current kept at
minimum values in all three phases throughout the entire starting
time, but disturbing direct current components are also
eliminated. This not only enables the 2-phase starting of motors
up to 55 kW (at 400 V) but also avoids the current and torque
peaks which occur e.g. with star-delta (wye-delta) starters.
The SIRIUS 3RW40 soft starters are suitable for starting
explosion-proof motors with "increased safety" type of protection
EEx e according to ATEX Directive 94/9/EC.

Note:
The specified short-circuit breaking capacities Iq in kA
are covered by combination tests. Smaller motor starter
protectors/circuit breakers from the same series can be used at
any time as smaller ones trip more quickly in the event of a short
circuit (unchanged short-circuit breaking capacity) and thus
protect the soft starter in any case. The dimensioning of the
short-circuit components must match the connected three-
phase motor, the short-circuit and overload requirements of
the application, and the line protection for the cables used.

■ Overview
More information

Industry Mall, see www.siemens.com/product?3RW30 www.siemens.com/tstcloud/?node=3rw30

https://support.industry.siemens.com/cs/ww/en/view/101494917
Conversion tool, see www.siemens.com/conversion-tool

The SIRIUS 3RW30 Basic Performance soft starters are suitable

for soft starting of three-phase asynchronous motors.
Thanks to 2-phase control, not only is the current kept at
minimum values in all three phases throughout the entire starting
time, but disturbing direct current components are also
eliminated. This not only enables the 2-phase starting of motors
up to 55 kW (at 400 V) but also avoids the current and torque
peaks which occur e.g. with star-delta (wye-delta) starters.

Note:
The specified short-circuit breaking capacities Iq in kA
are covered by combination tests. Smaller motor starter
protectors/circuit breakers from the same series can be used at
any time as smaller ones trip more quickly in the event of a short
circuit (unchanged short-circuit breaking capacity) and thus
protect the soft starter in any case. The dimensioning of the
short-circuit components must match the connected three-
phase motor, the short-circuit and overload requirements of
the application, and the line protection for the cables used.

Note:
The specified short-circuit breaking capacities Iq in kA are
covered by combination tests. Smaller fuses than those
specified can be used at any time as smaller ones trip more
quickly in the event of a short circuit (unchanged short-circuit
breaking capacity) and thus protect the soft starter in any case.
The dimensioning of the short-circuit components must,
however, be suitable for the connected three-phase motor
and the line protection for the cables used.

For CLASS 10 applications, as an alternative to the gG class
full-range fuses for cable and line protection 3NA3 (F1), 3RV2
motor starter protectors can also be used, possibly with reduced
short-circuit breaking capacity (see page 6/99). In these cases,
optional line contactors can be dispensed with.

SIRIUS 3RF solid-state switching devices

The most reliable solution for any application
Compared to mechanical switchgear, our SIRIUS 3RF2
solid-state switching devices stand out due to their considerably
longer service life. Thanks to the high product quality,
their switching is extremely precise, reliable and, above all,
insusceptible to faults. With its variable connection methods
and a wide spread of control voltages, the SIRIUS 3RF2 family
is universally applicable. Depending on the individual
requirements of the application, our modular switchgear can
also be quite easily expanded by the addition of standardized
function modules.
Always on the sunny side with SIRIUS
Because SIRIUS 3RF2 offers even more:
• The space-saving and compact side-by-side mounting

of +60 °C.
• Thanks to fast configuration and the ease of mounting and
1-phase solid-state relay and 3-phase solid-state contactor startup, not only time but also expenses are saved.

SIRIUS 3RF2 solid-state switching devices have firmly
established themselves in industrial applications. They are used
above all in applications where loads are switched frequently – Spring-loaded terminals
mainly with resistive load controllers, with the control of electrical
heat or the control of valves and motors in conveyor systems.
In addition to its use in areas with high switching frequencies, Ring cable lug connection
their silent switching means that SIRIUS is also ideally suited
for use in noise-sensitive areas, such as offices or hospitals.

Note:
The use of 1-pole solid-state switching devices with converters,
power controllers or power regulators of loads in a three-phase
network in full-wave control mode is not recommended.
As mutual synchronization of the function modules is not
possible, fluctuations in the heating power are possible; there is
no optimum settling in particular with setpoint values < 50%.

Solid-state contactors for switching motors Switching functions

The solid-state contactors for switching motors are
"Instantaneous switching", because this method is particularly
suited for inductive loads. By distributing the ON point over the
entire sine curve of the mains voltage, disturbances are reduced
to a minimum.
Connection methods
You can choose between the following connection methods for
the solid-state contactors for switching motors:
Screw terminals
The screw connection system is the standard for industrial
controls. Open terminals and a plus-minus screw are just two
features of this technology. Two conductors of up to 6 mm² can
be connected in just one terminal.

circuits in the load feeder. Consequently, special precautions
have to be taken against destruction, depending on the type
of design.
Siemens generally recommends using SITOR semiconductor
fuses. These fuses also provide protection against destruction in
the event of a short circuit even when the solid-state contactors
and solid-state relays are fully utilized.

Door-coupling rotary operating mechanisms for harsh conditions
The door-coupling rotary operating mechanisms consist of an actuator, a coupling driver, an extension shaft of 300 mm in length
(8 mm x 8 mm), a spacer and two metal brackets, into which the motor starter protector/circuit breaker is inserted.
The door-coupling rotary operating mechanisms are designed to degree of protection IP65. For UL/CSA applications, they are
tested for enclosure types 1, 3R and 12. The door interlocking reliably prevents opening of the control cabinet door in the
ON position of the motor starter protector/circuit breaker. The OFF position can be locked with up to three padlocks.
Laterally mountable auxiliary releases and 2-pole auxiliary switches can be used.
The door-coupling rotary operating mechanisms thus meet the requirements for isolating functions according to IEC 60947-2.
With the optional 3RV2926-2Q tolerance compensation, an offset can be compensated when installing the door-coupling rotary
operating mechanism for harsh conditions.

Overload relays
SIRIUS 3RU2 thermal overload relays
3RU2 for standard applications
3RU21 thermal overload relays up to 100 A have been designed
to provide inverse-time delayed protection for loads with normal
starting against impermissibly high temperature rises due to
6 overload or phase failure.
An overload or phase failure results in an increase of the
motor current beyond the set rated motor current. Via heating

IC01_00403a
elements, this current rise heats up the bimetal strips inside
the device which then bend and as a result trigger the auxiliary
contacts by means of a tripping mechanism. The auxiliary
contacts then switch off the load by means of a contactor.
5 The break time depends on the ratio between the tripping
1
current and the current setting Ie and is stored in the form of
4 a long-term stable tripping characteristic curve, see

3 The "tripped" status is signaled by means of a switch position
indicator. The relay is reset manually or automatically after
a recovery time has elapsed.
The 3RU2 thermal overload relays are suitable for operation with

5 Selector switch for Manual/Automatic RESET and RESET button:
With this switch you can choose between Manual and Automatic
RESET. A device set to Manual RESET can be reset locally by
pressing the RESET button. A Remote RESET is possible using the
RESET modules (accessories), which are independent of size.
6 Connection for mounting onto contactors:
Optimally adapted in electrical, mechanical and design terms to the
contactors. The overload relay can be connected directly to the
contactor using these pins. Stand-alone installation is possible as
an alternative (in conjunction with a terminal support for stand-alone
installation).
A sealable transparent cover can be optionally mounted (accessory).
It secures the motor current setting against adjustment.

This current rise is detected by means of a current measuring

module (see page 7/137) and electronically evaluated by the
NSB0_01621d evaluation module which is connected to it. The evaluation
9 electronics sends a signal to the auxiliary contacts. The auxiliary
contacts then switch off the load by means of a contactor.
8 1 The break time depends on the ratio between the tripping
7 current and the current setting Ie and is stored in the form
2 of a long-term stable tripping characteristic curve, see
6 Characteristics. The "tripped" status is signaled by means
2 of a continuously illuminated red "OVERLOAD" LED.

The LED indicates imminent tripping of the relay due to overload,

current has been violated. In the case of the 3RB22 and 3RB23

Operating conditions
3RA2 load feeders are climate-proof. They are intended for
use in enclosed rooms in which no severe operating conditions
(such as dust, caustic vapors, hazardous gases) prevail.
Suitable covers must be provided for installation in dusty
and damp locations.

Communication link through AS-Interface
Connection of the load feeders to the higher-level control
system is possible not only through IO-Link but also through
AS-Interface. The AS-Interface connection is recommended
wherever load feeders are used in distributed applications.
In this case, too, a contactor with a voltage tap is required with
a corresponding 3RA2712 function module (various versions
for direct-on-line, reversing and star-delta (wye-delta) starters).
The devices are implemented in A/B technology, making it easy
to connect up to 62 feeders to an AS-i master (regardless of
whether they are direct-on-line, reversing or star-delta (wye-
delta) starters). This results in a significant reduction of wiring
compared to the conventional parallel wiring method.
The electrical connection is made using standard cables.

Very high operational reliability

The high short-circuit breaking capacity and defined shutdown
when the end of service life is reached mean that the
SIRIUS compact starter achieves a very high level of operational
reliability that would otherwise have only been possible with
considerable additional outlay. This sets it apart from devices
with similar functionality.
Safe disconnection
The auxiliary switches (NC contacts) of the 3RA6 compact
starters are designed as mirror contacts. This enables their use
for safe disconnection, e.g. EMERGENCY STOP up to SIL 1
(IEC 62061) or PL c (ISO 13849-1) or, if used in conjunction with
an additional infeed contactor, up to SIL 3 (IEC 62061) or PL e
(ISO 13849-1).

compared to the parallel wiring method.
Communication link through IO-Link
Up to four compact starters in IO-Link version (reversing
and direct-on-line starters) can be connected together and
conveniently linked to the IO-Link master through a standardized
IO-Link connection.
The IO-Link connection enables a high density of information
in the local range.
For details regarding the communication link using IO-Link,
see page 2/88 onwards.
The diagnostics data of the process collected by the 3RA6
compact starter, e.g. short circuit, end of service life, limit
position, etc., are not only indicated on the compact starter itself
but also transmitted to the higher-level control system through
IO-Link.
Thanks to the optionally available operator panel, which can be
installed in the control cabinet door, it is easy to control the 3RA6
compact starters with IO-Link from the control cabinet door.

and creepage distances required according
to UL 508.
Accessories for infeed using 3-phase busbar systems
The 3RV1915-1.B 3-phase busbars can be used as an easy,
time-saving and clearly arranged means of feeding
SIRIUS 3RA6 compact starters with screw terminals.
Motor starter protector sizes S00 and S0 can also be integrated.
The busbars are suitable for between two and five devices.
However, any kind of extension up to a maximum summation
current of 63 A is possible by clamping the tags of an additional
busbar (rotated by 180°) underneath the terminals of the
respective last circuit breaker.
Motor starter protectors S00 and S0 of the 3RV2 series can be
combined in any way. The motor starter protectors are supplied
by appropriate infeed terminals. Special infeed terminals are
required for constructing "Starters (Type E)" according to
UL/CSA.
The 3-phase busbar systems have touch protection but empty
connection tags must be fitted with covers. They are designed
for any short-circuit stress which can occur at the output side of
connected SIRIUS 3RA6 compact starters or motor starter
protectors.

3-phase infeed system (3RM19 3-phase busbar system)

The system permits an easy, time-saving and safe means of
feeding two or more 3RM1 motor starters. It can be used only
with motor starters with screw terminals and in combination with
8US1716-0RK00 adapters for mounting rails in the main circuit.
The maximum summation current must not exceed 25 A.
The primary infeed is connected via a 3-phase infeed terminal.

IC01_00169c
The busbars are available in three lengths, for two, three or five
motor starters. More than five devices can be connected by
clamping the connection tags of a second busbar underneath,
rotated 180°.
The 3-phase busbars have touch protection but empty 4
connection tags must be fitted with covers.

example, two 3-phase busbars (5-pole busbars) rotated 180° allow up
to nine 3RM1 motor starters to be connected. Contact with the unused
connection tags in unoccupied positions is prevented safely by
the covers.

• Configuration is made easier by the fine modular structure four-wire systems three-wire systems
with ET 200pro. When using the ET 200pro motor starters,
the parts list per load feeder is reduced to two main items:
the bus module and the motor starter. This makes the
ET 200pro ideal for modular machine concepts or solutions

• Expansions are easily possible through the subsequent
adding of modules. The innovative plug-in technology also
does away with the wiring needed up to now. Through the hot V V V

• With four locally acting inputs available on the High Feature
motor starter it is possible to realize autonomous special
functions which work independently of the bus and the higher-

controls or limit position disconnectors. In parallel with this,
the states of these inputs are signaled to the control system.

General data
Dry-running protection of centrifugal pumps with SIMOCODE pro in hazardous areas
With special versions of the current/voltage measuring modules,
SIMOCODE pro enables dry-running protection of centrifugal
pumps through active power monitoring and motor switch-off.
This applies to centrifugal pumps with progressive flow
characteristics, which are also suitable for pumping flammable
media and are also installed in hazardous areas. If the active
Video: Dry-running protection redefined with SIMOCODE pro power, and thus the flow rate, falls below a minimum value, the
motor – and thus the centrifugal pump – is switched off. When
determining the limit values to be monitored, the user is
supported by a menu-guided teach-in process in the
engineering software.

fail-safe disconnection of motors. A maximum of one
fail-safe digital module can be connected; it can be used
instead of a digital module.
The fail-safe expansion modules are equipped likewise with
two system interfaces at the front for making the connection
to other system components. Unlike other expansion
modules, power is supplied to the modules through
a separate terminal connection.
Note:
Please order connecting cable separately, see page 10/18.

Timing relays
General data

■ Overview
The SIRIUS 3RA28 function modules enable the assembly
of starters and contactor assemblies for direct-on-line and
star-delta (wye-delta) starting. They include the key control
functions required for the particular feeder, e.g. timing and
electrical interlocking. The function modules that function as
timing relays are mounted quickly and simply on SIRIUS
contactors – without any great wiring effort.
The SIRIUS 3RA28 solid-state time-delay auxiliary switches
which can be mounted on contactors are designed for contactor
coil voltages in the range from 24 to 240 V AC/DC (wide voltage
range). Auxiliary switches for control and alarm signals are used
specially for switching the smallest signals for electronics
applications. They are used, for example, for allowing a pump
or fan to run on, or for the delayed activation of a gate drive.
Simply by being plugged in place, the SIRIUS 3RT19 timing
relays enable different functionalities required for the assembly
of starters to be realized in the feeder. At the same time the
timing relays for mounting on contactors reduce the wiring work
7PV15, SIRIUS 3RP25 and SIRIUS 3RP20 timing relays required within the feeder and save space in the control cabinet.

For example, use of 3RP2560 for compressor control

Frequent starting of compressors strains the network, the

NSB0_00892d

17/28
prevents the compressor from being switched off immediately

Instead, the valve in the intake tube is closed and the

switched off.
The pressure switch controls the timing via B./A2.
A./A2
The control supply voltage is applied to A./A2 and the start
B./A2 contact B./A2 is open, i.e. there is no control signal on B./A2
when the control supply voltage is applied. The pressure switch
17/18 signals "too little pressure in system" and starts the timing by way
Y of terminal B./A2. The compressor is started, enters * operation,
and fills the pressure tank.
NSB0_00893d

17/28
When the pressure switch signals "sufficient pressure", the
17/38
control signal B./A2 is applied, the idling time (coasting time)
is started, and the compressor enters no-load operation for the
tY 50 ms
set period of time from 30 to 600 s. The compressor is then
tIdling switched off. The compressor is only restarted if the pressure
switch responds again (low pressure).

SIRIUS 3RR21, 3RR22 monitoring relays for mounting on 3RT2 contactors
Current and active current monitoring

■ Overview
The 3RR2 current monitoring relays can be integrated directly in
the feeder by mounting on the 3RT2 contactor; separate wiring
of the main circuit is therefore superfluous. No separate
transformers are required.
For a line-oriented configuration or simultaneous use of an
overload relay, terminal supports for stand-alone installation are
available for separate DIN-rail mounting.
Versions
Basic versions
The basic versions with 2-phase apparent current monitoring,
a CO contact output and analog adjustability provide a high
level of monitoring reliability especially in the rated and overload
range.
