LC3-D series star delta reduced voltage starter is suitable for starting motor in the circuit of AC 50/60HZ,voltage up to 660V and current up to 95A. It is provided with a timer for automatic changeover of star-delta to reduce the voltage and current of motor starting. Ty...
The Star/Delta (or Wye/Delta) starter is one of the lowest cost electromechanical reduced voltage starters that can be applied and this is why it has been so popular. The Star/Delta starter complied with the regulations, but did not achieve the desired results. ...
The most critical part of connecting a star-delta starter ismaking the actual load connections to the motor. An improper connection generally results in the motor stopping and reversing direction when transition is made from star to delta. It is recommended that the circuit and components be numbe...
