SIRIUS 3RW50 soft starters device family
SIRIUS 3RW50 Basic Performance soft starters are the compact solution for standard applications. They have 2-phase motor control and cover the performance range from 75 to 315 kW (at 400 V).
Optional HMI modules for installation in the control cabinet door, laterally mountable communications modules (PROFINET, PROFIBUS, EtherNet/IP and Modbus) and either an analog output or thermistor motor protection ensure maximum flexibility.
With their modern hybrid switching technology, the SIRIUS 3RW50 soft starters offer efficient switching for long-term, energy-saving use.
