The Siemens 3RW4455-6BC45 is a SIRIUS soft starter designed for smooth and controlled starting of three-phase induction motors. It offers reduced mechanical stress on the motor and connected machinery by limiting inrush current. This model is rated for operation at 500V, with standard values of 693A and 500kW, and inside-delta values of 1200A and 800kW.
This soft starter is suitable for a wide range of industrial applications, including pumps, fans, compressors, and conveyors, where soft starting is required to prevent system shock and wear. It operates on 400-600V AC mains voltage with a 230V AC control voltage and features screw terminals for secure connections. Please note that this product is phased out, with the SIRIUS 3RW5 series being its successor.
