Product description

The Siemens SIRIUS 3RW30 Soft Starter (Part Number: 3RW3014-1CB04) is designed to provide smooth and controlled starting of three-phase induction motors. This Size S00 starter has a rated current of 6 A and can handle a motor power of up to 3 kW at 400 V. It features a wide control voltage range of 200-460 V AC and a separate 24 V AC/DC (UC) control circuit for versatile integration into various power systems. The unit utilizes screw connections for reliable and secure electrical termination.

This soft starter is ideal for applications where reducing mechanical stress on machinery during motor startup is important, such as conveyor systems, pumps, fans, and compressors. By limiting the inrush current, it helps to protect motor windings, reduce voltage dips on the power line, and extend the lifespan of connected equipment, finding use in general manufacturing, material handling, and building automation.
