Soft starter SIRIUS 3RW40

Siemens Sirius 3RW40 is designed for high power 250 kW asynchronous motors. Siemens Soft starter allow easily start, allows you to protect the engine against overload, reduces the current rate, which makes the utilize of equipment low-priced. The data models apply features unique to this power range: semiconductor motor overload protection and built-in appliance protection, controllable current qualification and control the 2-phase technique. The Soft starters 3RW40 are part of the SIRIUS modular system. Consequently, they have pinpoint sizes and wiring diagrams. Due to their special compact size, Siemens soft starters are half the size of star-delta starters, thereby they take up minimum space in the control cabinet. At the contactor, they are applied as safety-free starting union for electric engines.
