Soft starter SIRIUS 3RW40

Siemens Sirius 3RW40 is intended for high power induction engines (up to 250 Kilowatt). The device provides light start-up, protects the engine against overload, reduces the current consumption, inexpensive than utilize of the facilities. The data devices apply features out-and-outer to this capacity diapason: semiconductor engine overload defense and built-in protection devices, adjustable current limiting and control the 2-phase technique. Siemens 3RW40 soft starters are the portion of the SIRIUS modular system. Consequently, they have pinpoint dimensions and connection diagrams. Thanks to its special dense dimensions, Siemens soft starters are half as much the size of star-delta starters, thereby they take up minimal space in the monitoring cabinet. At the contactor, they are applied as safety-free starting combinations for starting engines.
