SIEMENS-Soft Starters,

Basic Performance

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 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.
