Soft starter SIRIUS 3RW40

Siemens Sirius 3RW40 is designed for high power 250 kW asynchronous motors. The soft starter allow easily start-up, allows you to protect the motor from overloads, lower the current expenditure, which makes apply of apparatus cheaper. The data models are equipped with features unique to this power diapason: solid-state motor overburden protection and built-in device protection, controllable current qualification and two-phase control technique. Siemens 3RW40 soft starters are sections of the SIRIUS modular system. Consequently, they have pinpoint sizes and connection schemes. Due to their particularly compact dimensions, Siemens soft starters are half the dimension of star-delta starters, thereby they take up minimum place in the control cabinet. At the contactor, they are utilized as safety-free starting combinations for starting engines.
