The SIEMENS 3RW3013-1BB04 is a SIRIUS soft starter designed to control and limit inrush current for motors up to 1.5 kW at 400 V, with a nominal current of 3.6 A. It supports supply voltages from 200–480 V AC and operates reliably to 40 °C, using 24 V AC/DC control and screw terminal connections for straightforward wiring. Use it to reduce mechanical stress during motor startup, shorten commissioning time, and protect electrical systems from voltage dips. Compact and simple to install, it’s suited for applications where smooth, repeatable starts and basic motor protection are required.
