Soft starter SIRIUS 3RW40

Siemens Sirius 3RW40 is designed for high power asynchronous engines (250 kW). The device give easy start-up, protects the motor from overloads, reduces the current expenditure, which makes the utilize of equipment cheaper. These models are equipped with features out-and-outer to this capacity range: semiconductor motor overburden defense and integral appliance protection, controllable current limitative and 2-phase monitoring technique. Siemens 3RW40 soft starters are part of the SIRIUS modular system. As a result, they have identical dimensions and wiring schemes. Due to their especially dense size, Siemens soft starters are half the size of star-delta starters, thereby they take at minimal space in the control cabinet. At the contactor, they are applied as protective infinite combinations for starting engines.
