Soft starter SIRIUS 3RW52

Soft starters were designed for soft starting of three-phase asynchronous electric engines up to 710 kW with standard connection and 120 Kilowatt with star-delta liaison. In contrast to another soft starter, this device has extra progressive features such as pump cleaning, reverse operation, DC braking, motor warm-up, arrow function, programmable inputs and outputs. The declared functions have been especially designed to proposal superior user experience. Thanks to a help of a removable panel (with local interface and micro SD card slot) and detachable communication modules (PROFINET, PROFIBUS, Modbus), they provide high flexibility. Thanks to its wide range of purposes, the SIRIUS 3RW55 soft starters allow you to cope perfectly even with the majority, heavy, on/off conditions of the electric engine.
