Soft starter SIRIUS 3RW40

The Soft starter Sirius 3RW40 is intended for high power asynchronous engines (up to 250 Kilowatt). Siemens Soft starter provides easy start, protects the engine from overloads, lower the current expenditure, which do the utilize of equipment cheaper. The data devices use features out-and-outer to this output range: solid-state engine overload defense and inbuilt device protection, controllable current limiting and control the two-phase method. The soft starter Siemens 3RW40 are part of the SIRIUS modular system. As a result, they have pinpoint sizes and wiring diagrams. Thanks to its particularly compact dimensions, Siemens soft starters are half as much the size of star-delta starters, thus they take up limited space in the monitoring cabinet. At the contactor, they are applied as protective infinite combinations for starting engines.
