Siemens Motor Starter, Soft Start, 400 kW, 480 V ac, 3 Phase

The Siemens SIRIUS 3RW52 family provide soft actuators are ideal for standard conditions and the load. They comprise selection of power & give 3-phase control. High flexibility is provided with extra HMI units, insertion contact units, and either an analog output or thermistor motor protection. The built-in bypass circuit closer enables working in a hybrid mode, which offer efficient switching for long-term & reducing power intake and heating of the SCP. The 3RW52 soft starter unceasingly regulate the voltage. As a consequence, the torque and amperage values little by little they rise. To create reliable machines, our new SIRIUS 3RW52 soft starters offer you intelligent functions such as automatic parameterization, pump cleaning, and condition monitoring.
