Description

SIRIUS 3RW40 for Standard Applications

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.

Advantages at a glance
Uniform connecting system with screw or spring-loaded terminals
Space-saving, clear layout in the control cabinet thanks to small, compact design
Integrated bridging (bypass)
Inherent protection and protection against motor overload without additional wiring
Optional thermistor motor protection
Avoidance of peak inrush current thanks to adjustable current limitation
Simple and fast commissioning
Certified according to ATEX standards with sizes S0 - S12
