for Motor 3Phase 18.5kW 400V 50/60Hz.
for Motor 1Phase 11kW 230V 50/60Hz.
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 wye-delta starters.
