The integrated bypass allows a very compact construction and ensures low heat dissipation in the control cabinet. Intelligent monitoring functions protect the soft starter against overheating and the motor against overload. In addition, you can limit the current during startup to a settable maximum value. Thanks to 3-phase control, particularly suitable for high motor outputs and inside-delta circuits. The innovative torque control ensures ideal motor startup. Integral display for fast commissioning and status displays. Provision of energy data via PROFINET, for example. Worldwide approvals (e.g. IEC and UL/CSA).The 3RW soft starters are available for supply systems up to 690 V in a wide performance range with different control supply voltages and all with both screw and spring-type terminals.
