The Sirius 3RW40 soft starter up to 250 kilowatts (at 400 V) are appropriate for standard three-phase use and are designed for soft start/stop of three-phase induction engines. It's prevent current peaks and torque that occur when applying "star-delta" starters. Soft starters are organized with optimal functionality. The built-in bypass contact system decreases the power losses during exploitation, whereby the components do not super heat. The overload trip time can be set with the 4-step rotary switch. Thanks to the adjustable amperage limitation, the motor is surely covered even from a surprise growth in current strength. Three LEDs are utilized to display the operating mode, ineffective trip times (trip class), no load, overheating. Main typical applications: pumps, air conditioning systems, conveyors, chillers, working mechanisms, mixers.
