Circuit-breakers, switch-disconnectors
Current range Selection criteria for IZM circuit-breakers

The new open circuit-breaker IZM covers the entire range from 800 A … 6300 A Fundamental criteria for the selection of circuit-breakers:
with just two frame sizes. The compact frame size IZM1 extends the rated current • Max. short-circuit at the point of installation of circuit-breaker Ik max: this value

Dimensions • Rated current In which should flow through the respective branch circuit: this
value may not be greater than the maximum switch rated current of the circuit-
breaker. The rated current is defined with the IZM with the rated current module
The IZM devices have the same height and depth across their entire current range. (exception: overcurrent release for system protection XZMA).
Only their device varies depending on the number of poles and the frame size. • Ambient temperature of the circuit-breaker: this is generally the internal control
panel temperature. Observe the derating table with increased ambient tempe-

accessible from the front and flanged connections. • Protection functions of the circuit-breaker: This is determined by the selection
of the respective overcurrent release.
Control units
Documentation
The IZM features microprocessor-controlled control units as standard. Five different
control units are available for selection and thus offer optimum protection for your Operating manual AWB1230-1407D/GB, part no. 232792
system: From simple system protection with overload and short-circuit release ex-
tending to a digital circuit-breaker with graphic display and the option of setting up Approvals
time-discriminating networks.
Approved circuit-breakers IZM can be found under “Approvals for world markets”.
Control circuit connections

The built-in auxiliary switches are connected to the male connector on the switch.
Irrespective of the mounting type, the customer connects the auxiliary power circuits
to the control circuit plugs at the top of the circuit-breaker. The standard terminals
are screw-type; spring-loaded terminals are optional.
ON fixed mounting units, the control circuit plugs are fitted directly to the plug con-
nectors on the switch and are coded against accidental reversal.
To allow withdrawable units to be moved, a sliding contact module is fitted between
switch and mounting. The sliding contact module allows a secure connection of the
control circuit cable connectors in the “connected” and “test” positions of the
switch.

Modular design

Because components are installed from the front, retrofitting accessories is especial-
ly quick and easy. This allows you to respond flexibly to changing requirements
within your system.

Communication-capability

With their communication-capability, the IZM circuit-breakers open up new possibi-

lities in power distribution. Providing and transmitting all important operational in-
formation, they increase system transparency and shorten the response times to
states such as overcurrent, phase asymmetry and overvoltage. A rapid intervention
in a process can, for example, prevent downtimes and help to schedule maintenance
activities and therefore boost plant availability.
Internal system bus
The IZM universal and digital circuit-breakers contain an internal system bus as
standard, which connects all intelligent components of the circuit-breaker.
Through the communications interface, the information from the intelligent compo-
nents can then be transmitted through PROFIBUS-DP, for example with the IZM-
XCOM communication module.
Expansion modules for the internal system bus:
External add-on modules can be connected to the IZM circuit-breakers through the
internal system bus without extensive additional wiring. Digital input modules and
digital and analog output modules are available for this purpose. A further module
implements reduced-time selectivity control between IZM circuit-breakers.

Communication module

from 630 A to 6300 A

The IZM-XCOM-DP communication module enables connection of the IZM circuit-
g c breaker to the PROFIBUS-DP. A PROFIBUS master can communicate with the IZM
via the DP and DPV1 protocols for monitoring purposes.
Maintenance information received on time (e.g. via the operating time/hours or via
the wear and usage of the main contacts) enables the user to prevent system stand-
stills. With threshold violation signals, users can take preventative measures before
f it comes to a trip. For later analysis with the IZM-XEM-PG parameter assignment
module, the relevant data generated when a trip takes place is saved in the device
(for example tripping current with date and time).
Because the communication module is attached to the frame of the circuit-breaker,
the built-in temperature sensor measures the temperature inside the control panel.
The switch position is transmitted to PROFIBUS through three microswitches in the
underside of the communication module (operating, test or isolated position).
All microswitches that record information about the state of the circuit-breaker are
e d installed on or connected to the breaker status sensor (BSS module) for signalling
internal switching states. The module provides this digital information (ON, OFF,
status of the spring energy store, availability, voltage release) on the built-in system
bus. A further temperature sensor determines the temperature in the circuit-breaker.
This reading is also made available through a bus line.

Control voltage supply

The basic functions of the electronic overcurrent release do not require auxiliary po-
wer. With the “Universal” and “Digital” release it is possible to use additional func-
tions which necessitate a data exchange via the internal system bus. These devices
are fitted with the internal system bus as standard. For data communications, an ex-
ternal 24 V DC power supply is required, which must fulfil the following conditions:
• Primary switched-mode power supply unit
• 24 V DC, G 3 %
• Rated output current: 5 A per circuit-breaker with the greatest possible number
of external expansion modules.
For example, you can use the Moeller switched-mode power supply unit SN4-050-
BI7, Article no. 200034.
Connection to control circuit connections X8:3 and X8:4 or to one of the expansion
modules. The various components are then supplied with power through the inter-
nal system bus connection.

• Communication module
• Expansion modules
• Measuring module
• 4-line display or graphic display
• Parameter assignment module

With the 4-line display, the phase currents and the set parameters can be viewed
without an external power supply, as soon as the load exceeds 80 A (at IZM...1(2)...)
or 200 A (with IZM...3...) on the main circuit.

If the parameter assignment module is used in Offline mode (i.e. without connection
to an electronic release), it can not be supplied through the internal system bus. In

Circuit-breakers, switch-disconnectors

ZSI module

Where full selectivity at low delay times is an issue even if the circuit-breakers are
arranged in hierarchical groups, the ZSI modules have the solution. They are used to
connect the circuit-breakers with each other.
If a short-circuit occurs, each circuit-breaker through which short-circuit current
from 630 A to 6300 A

flows determines whether the adjacent circuit-breaker on the next lower level is also
affected. This allows the exact location of the short-circuit to be identified and only
the circuit-breaker immediately upstream of the fault location is tripped.
With the microprocessor-controlled “delayed selectivity control”, the tripping delay
of these upstream circuit-breakers can be reduced to up to 50 ms.

Digital output module with rotary coding switch

This module can output 6 binary data units concerning the switching state (trip cau-
ses and warnings) of external switching devices (e.g. lamps, horns, klaxons) or for
switching off further system components (e.g. frequency inverters).
Various versions of digital output modules are available, both with and without a
rotary coding switch. Modules with a rotary coding switch allow selection between
two signal blocks, each with six defined assignments, and an additional response
delay.
The digital output modules are available as versions with opto-coupler outputs (N/
O contact, 150 mA) or with relay outputs (changeover contacts up to 10 A). Up to
two modules of this type can be connected to an IZM.

Digital output module, configurable

For high-performance solutions, the configurable output module is available. With

this unit, any event on the internal system bus can be switched directly on one of six
available outputs or three of these outputs can be assigned with up to six events
(“OR” operation). The module can be configured with the IZM-XEM-PG or IZM-
XEM-PGE parameter assignment module (with Ethernet interface).
As for the output modules with rotary coding switch, a relay version are available.
Only one module of this type can be used per IZM. Parameter assignment module
