A basic starter configuration comprising circuit breaker and contactor, without step or soft starting, is the suitable solution for drives such as pumps, saws etc. But also large drives, for example, on amusement rides and rollers, can be directly started with SIRIUS. A direct start is characterized by the high tightening torque of the motor upon starting.

SIRIUS completely covers the performance range between 0.06 and 250 kW at 400 V.
