Which circuit?
Using the inline circuit involves the lowest wiring outlay. If the soft
starter to motor connections are long, this circuit is preferable.
The wiring complexity is twice as high when using the inside-
delta circuit, but a smaller device can be used with the same
rating. Thanks to the choice of operating mode between the
inline circuit and inside-delta circuit, it is always possible to
select the most favorable solution.
The braking function is possible only in the inline circuit.
The inside-delta circuit cannot be used in 690 V line supplies.

Note:
The service factor or measurement inaccuracies have been
taken into account, for example, 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 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 690 V systems, in motor feeder tests with soft starters demon-
strable short-circuit breaking capacities can only be achieved
with the use of 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 speci-
fied 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.

Note:
The specified short-circuit breaking capacities Iq in kA are
covered by combination tests. Smaller fuses than those speci-
fied 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.

SOFT STARTERS
Note:
The service factor or measurement inaccuracies have been
taken into account, for example, 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 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.

Note:
The specified short-circuit breaking capacities Iq in kA are
covered by combination tests. Smaller fuses than those speci-
fied 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.

The SIRIUS 3RW40 Basic Performance soft starters are suitable

for soft starting and stopping of three-phase asynchronous
motors.
Thanks to two-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 two-phase starting of
motors from 7.5 to 75HP @ 480V but also avoids the current and
torque peaks which occur e.g. with wye-delta starters.
The SIRIUS 3RW40 soft starters are suitable for the starting of
explosion-proof motors with "increased safety" type of protection
EEx e according to ATEX Directive 94/9/EC.

The SIRIUS 3RW30 Basic Performance soft starters are suitable

for soft starting of three-phase asynchronous motors.
Thanks to two-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 elimi-
nated. This not only enables the two-phase starting of motors
from 1.5 to 75HP @ 480V but also avoids the current and torque
peaks which occur e.g. with wye-delta starters.

SINAMICS G120X
Introduction

SINAMICS G120X
An infrastructure drive for pumps, fans
and compressors
Siemens introduces an exciting new addition to the existing
SINAMICS product portfolio — the G120X — an “infrastructure”
drive up to 700 hp (630kW), which is targeted for pump, fan
and compressor applications in the water / wastewater, HVAC,
irrigation / agriculture and industrial chiller and refrigeration
industries.
Seamless process for higher efficiency
SINAMICS G120X is simple, seamless, cost- and energy-
efficient, robust, reliable and fit for digitalization. It integrates
easily into existing applications, works with any standard motor
(induction, synchronous and synchronous reluctance) and can be
configured for cost-optimization and resource-saving operation
which ultimately helps reduce total cost of ownership. SINAMICS
G120X meets all the latest industry standards with regard to
energy efficiency and product safety, and offers enhanced safety
with SIL3-rated safety functions and up to 100kA short-circuit
current rating according to new UL61800-5-1 design.
