Soft starter SIRIUS 3RW40

Siemens Sirius 3RW40 is designed for high power induction engines (up to 250 Kilowatt). Siemens Soft starter give easy start-up, protects the engine from overloads, reduces power consumption, which makes the utilize of apparatus cheaper. These models apply features unusual to this output diapason: solid-state motor overburden protection and built-in device protection, adjustable current qualification and control the 2-phase technique (polarity balance). Siemens 3RW40 soft starters are sections of the SIRIUS modular system. As a result, they have identical sizes and connection schemes. Thanks to their special dense size, Siemens soft starters are half as much the dimension of star-delta starters, thereby they take at limited space in the control cabinet. At the contactor, they are used as protective infinite conjunction for electric engines.
