Siemens 3RW3014-1BB14 Soft Starter rated at 3kW, 6.5A for a 110..240V AC/ DC rated control Supply Voltage. Rated Operational Voltage 200 .. 480 V Rated Operational Current 6.5 A Rated Power of Induction Motors for a rated operational voltage of 400V 3 kW Rated Power of Induction Motors for a rated operational voltage of 230V 1.5 kW Rated Control Supply Voltage 110 .. 240 V AC/ DC Siemens 3RW30 Soft Starters reduce the motor voltage through variable phase control and increase it in ramp-like mode from a selectable starting voltage up to mains voltage. Soft Starters during starting devices limit the torque as well as the current and prevent the shocks which arise during direct starts or wye-delta starts. In this way, mechanical loads and mains voltage dips can be reliably reduced.
