Soft starter SIRIUS 3RW40

The Sirius 3RW40 soft starter is intended for high power 250 Kilowatt asynchronous motors. Siemens Soft starter give easily start, allows you to protect the motor from overloads, reduces power rate, which makes apply of equipment cheaper. These models apply features unusual to this energy range: solid-state motor overload security and inbuilt appliance protection, adjustable current limitative and control the 2-phase method (polarity balance). Siemens 3RW40 soft starters are the portion of the SIRIUS modular system. Consequently, they have identical dimensions and wiring schemes. Thanks to their particularly compact dimensions, SIRIUS 3RW40 soft starters are half the dimension of star-delta starters, thus they take up limited place in the control cabinet. Together with the contactor, they are utilized as protective infinite union for starting motors.
