Siemens SIRIUS 3RW4456-2BC45 Soft Starter - Phased Out
The Siemens 3RW4456-2BC45 is a SIRIUS soft starter designed for smooth and controlled starting of three-phase asynchronous motors. It offers standard starting currents of 780 A and inside-delta currents of 1351 A at 500V and 40°C. This unit operates on 400-600 V AC and features spring-type terminals for secure connections.
This soft starter is crucial for applications where high starting currents need to be managed to prevent mechanical stress on machinery and reduce power system load. It is suitable for heavy-duty applications such as conveyors, pumps, and compressors. Please note, this is a phased-out product.
