Soft starter SIRIUS 3RW40

The Sirius 3RW40 soft starter is intended for high power asynchronous motors (up to 250 Kilowatt). Siemens Soft starter provides easily start, protects the motor against overload, reduces power consumption, inexpensive than utilize of the equipment. These models apply features unusual to this power range: semiconductor motor overburden protection and built-in protection devices, adjustable current limitative and two-phase control method (polarity balance). The Soft starters 3RW40 are sections of the SIRIUS modular system. As a result, they have identical sizes and connection diagrams. Thanks to their special dense dimensions, SIRIUS 3RW40 soft starters are half the size of star-delta starters, thereby they take at minimal space in the control cabinet. Together with the contactor, they are utilized as protective infinite union for electric engines.
