Soft starters 250 kilowatt are suitable for standard three-phase use and are designed for soft on/off of 3-phase induction engines. They prevent current peaks and torque that happen when using "star-delta" starters. The Sirius 3RW40 is appointed with optimum operating. Fitted shunt contact system decrease the power losses in operation, so the constituent element does not warm-up. On-off time can be set overload tripping 4-step rotary switch. Thanks to the managed amperage limitation, the engine is reliably protected even from a surprise growth in current strength. The 3 LEDs are utilized to display the operating mode, ineffective trip times, no load, device failure. Main typical applications: pumps, air conditioning systems, escalators, compressors and coolers, working mechanisms, mixers.
