سافت استارتر - نرم راه انداز 3RW40

SIRIUS 3RW40 is the star among our standard soft starters. Thanks to its innovative control method, it is not just the only 2-phase-controlled soft starter in the world for use in the power range up to 250 kW (at 400V) – respectively 300 hp (at 460V) – because of its especially compact design, it ensures a space-saving, clear layout in the control cabinet. It is therefore more than a mere functionally expanded addition to our 2-phase-controlled series of SIRIUS 3RW30/31 soft starters.

The new 3RW40 soft starters in the lower power range from 5.5 - 55 kW (with 400 V) in sizes S0 to S3 expand the performance spectrum of the 3RW40 soft starters. They represent the compact and price-attractive alternative to start-delta starters.
