Miniature Soft Starter
Soft starter SIRIUS 3RW30 for standard applications for the soft starting of three-phase asynchronous motors.
Soft starting, reduction of current peaks, prevention of supply voltage fluctuations during startup, reduction of load on the power supply network, reduction of mechanical load in the drive, considerable saving of space and wiring compared to star-delta (wye-delta) starters and frequency converters, maintenance-free switching and extremely easy handling. The integrated bypass allows a very compact construction and ensures low heat dissipation in the control cabinet. Worldwide approvals (e.g. IEC and UL/CSA).
The 3RW soft starters are available for supply systems up to 690 V in a wide performance range with different control supply voltages and all with both screw and spring-type terminals. For the 3RW30/40 there are additional versions with 24 V control supply voltage. Some of the 3RW40 up to size S3, and all 3RW44 units also offer thermistor motor protection.
With the optional link module, the soft starters can be attached to the circuit breakers, even for the versions with spring-type terminals.
Simple, efficient and always up to date - SIRIUS modular system.
