Siemens SIRIUS Soft Starter 47A, 22kW (Phased Out).
The Siemens SIRIUS 3RW4424-1BC44 is a soft starter designed to reduce the mechanical and electrical stress on machines and systems during motor start-up. For a 400V system at 40°C, it handles a standard current of 47A and a motor power of 22kW. In an inside-delta connection, it supports 81A and 45kW. The unit operates on 200-460V AC with a 230V AC control voltage, featuring screw terminals for connections.
This specific model is a phased-out product. The preferred successor is the SIRIUS 3RW5524-1HA14. Soft starters are crucial for applications where smooth acceleration is required, such as in conveyor systems, pumps, fans, and compressors, helping to prevent jolts and save energy.
