Siemens SIRIUS 3RW44 Soft Starter
The Siemens SIRIUS 3RW4456-6BC45 is a high-feature soft starter designed for the soft starting and ramp-down of three-phase asynchronous motors. It provides smooth acceleration, reduces current peaks, and minimizes mechanical stress on the motor and connected equipment. This unit is rated for 400-600 V AC and uses a 230 V AC control supply voltage. It features screw terminals for easy and secure connections.
Key specifications include a standard operating current of 780 A and a power rating of 560 kW at 500 V and 40°C. In an inside-delta configuration, it can handle 1351 A and 900 kW. The integrated bypass contact allows for a compact design and reduces heat dissipation in the control cabinet. Intelligent monitoring functions protect the soft starter from overheating and the motor from overload.
