Soft starters at 400 V are appropriate for standard 3-phase applying and are designed for soft start/stop of 3-phase asynchronous engines. They prevent current peaks and torque that occur when applying "star-delta" starters. The Sirius 3RW40 is equipped with optimal functionality. Fitted shunt contact system decrease energy losses in operation, so the components do not overheat. Use time can be set overload tripping four-step rotary switch. Thanks to the managed amperage limit, the engine is surely protected even from an unexpected growth in current strength. The 3 LEDs are utilized to mapping the possible errors, ineffective trip times (trip class), phase failure, overheating. Main types applications: construction machines, air conditioning systems, escalators, compressors and coolers, centrifuges, agitators.
