Soft starters up to 250 kilowatts (at 400 V) are appropriate for standard 3-phase use and are allotted for soft start/stop of 3-phase induction motors. It's prevent current peaks and torque caused by the utilize of star-delta starters. Soft starter Siemens 3RW40 is equipped with optimum operating. The built-in shunt contact system reduces the power losses during working, so the components do not overheat. With the four-step rotary switch, the overload trip time may be install. Thanks to the managed amperage limitation, the engine is reliably protected yet from a surprise increase in current strength. The 3 LEDs are utilized to mapping the operating mode, ineffective trip times (trip class), no load, device failure. Main types applications: pumps, presses, assembly lines, compressors and coolers, working mechanisms, mixers.
