Soft starter SIRIUS 3RW40

Siemens Soft starter 3RW40 is intended for high power 250 Kilowatt asynchronous engines. Siemens Soft starter allow easy start, protects the motor from overloads, reduces the current rate, which do apply of devices low-priced. These devices use features unique to this capacity diapason: solid-state engine overburden protection and built-in arrangement protection, regulating current qualification and control the 2-phase technique (polarity balance). Siemens 3RW40 soft starters are the portion of the SIRIUS modular system. As a result, they have pinpoint dimensions and connection diagrams. Due to their particularly compact size, Siemens soft starters are half as much the size of star-delta starters, so they take at minimal place in the control cabinet. Together with the contactor, they are used as safety-free starting conjunction for starting motors.
