The Sirius 3RW40 soft starter 250 kW are suitable for standard three-phase use and are designed for soft on/off of three-phase asynchronous motors. They avoid the inrush current and torque that happen when applying "star-delta" starters. The Sirius 3RW40 is organized with optimum operating. The built-in shunt contact system diminishing energy losses during operation, so the components do not super heat. With the 4-step rotary switch, the overload trip time can be set. Thanks to the adjustable amperage limit, the engine is surely covered yet from a sudden growth in amperage. The 3 LEDs are used to display the operating mode, ineffective trip times, no load, overheating. Main types applications: pumps, air conditioning systems, conveyors, compressors and coolers, working mechanisms, agitators.
