Soft starter SIRIUS 3RW40

Siemens Sirius 3RW40 is intended for high power 250 Kilowatt asynchronous motors. The soft starter give easy start-up, protects the motor from overloads, lower the current consumption, cheaper than utilize of the facilities. The data models apply features out-and-outer to this energy diapason: solid-state motor overburden defense and integral protection devices, adjustable current limiting and 2-phase monitoring technique. The Sirius 3RW40 are the portion of the SIRIUS modular system. As a result, they have pinpoint sizes and connection diagrams. Thanks to its special dense size, SIRIUS 3RW40 soft starters are half the size of star-delta starters, thereby they take up minimal place in the control cabinet. At the contactor, they are used as protective infinite conjunction for starting engines.
