Siemens SIRIUS 3RW Family | 3RW52 Series — Next Gen. General Performance Soft-Starters:

The SIRIUS 3RW52 soft starter is the ideal alternative to star-delta starters. As an all-rounder, it is applicable for any type of drive. With ideal 3-phase motor control, they cover the performance range from 5.5 kW to 560 kW (at 400 V). With optional HMI modules and plug-in communication modules (PROFINET, PROFIBUS, Modbus) and either an analog output or thermistor motor protection, they offer maximum flexibility. With their modern hybrid switching technology, the SIRIUS 3RW52 soft starters offer efficient switching for long-term, energy-saving use.

To create reliable machines, our new SIRIUS 3RW52 soft starters offer you intelligent functions such as automatic parameterization, pump cleaning, and condition monitoring. So if you’re designing a new machine in the near future, we’ll support you with sophisticated solutions for pumps, compressors, fans, and conveyor belts, or with process development; regardless of whether your machine is intended for the automotive, wastewater, or the food and beverage industry.
