The Star-delta connection is used in order to reduce high currents when starting electric motors. With this 2-stage starter the inrush current (star circuit) is reduced by 1/3 of the height to be expected when starting the motor directly. The Condor CSDU Star/delta connection offers, in due consideration of the relevant standards, the possibility of economically operating motors with a switching capacity greater than 4 kW using public mains networks. With this 2-stage starter the inrush current (star circuit) is reduced by 1/3 of the height to be expected when starting the motor directly. The torque is equally reduced during start-up phase. During the start-up phase (1 – 32 seconds), a special change-over relay with a contact switching time of 50 ms, guarantees reliable change over from star to delta operation. During continuous operation, all motors connected to the Star/delta connection are protected by a manual motor starter with thermal and magnetic trip. Standard executions contain a manual motor starter and an on / off switch for the control circuit.
