Soft starter SIRIUS 3RW30

SIRIUS 3RW30 soft starter is specially destined for 3-phase asynchronous engines where the power not over 55 kW. The arrangement has an enough suite of options that makes it easy to start the engine. The soft starters give easy operation for the linked engines, reducing the torque. The power supply is covered from unsafe peaks by reducing current consumption in the start time. At the contactor, they are utilized as safety-free starting conjunctions for electric motors. SIRIUS 3RW30 electronic soft starters from the SIRIUS modular system: small, inexpensive and easy to combine with SIRIUS overload relays. Siemens Sirius 3RW soft starters allow soft start and stop for 3-phase asynchronous motors. The star-delta starters have hitherto been used, for example, in belt conveyors, compressors, textile machines, and others.
