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.

3RW44 for High-Feature Applications
A compact design for maximum functionality
Thanks to its outstanding functions, the SIRIUS 3RW44 all-round talent handles difficult start-up and deceleration processes in a simple and, above all, gentle manner. With its innovative torque control system, it can be used for drives with a power output up to 710 kW at 400 V – respectively 950 hp at 460 V – in an inline circuit or up to 1200 kW at 400 V – respectively 1700 hp at 460 V – in an inside-delta circuit. Designed for simple handling, the functions are exceptionally easy to use.
Advantages at a glance
-
Optimum acceleration due to torque control
-
Simple and fast commissioning thanks to user-friendly display
-
Savings in size and costs due to optional inside-delta circuit
-
Simple integration in higher-level control units via PROFIBUS
