Motor Starter

Our Motor Starters consist of a single contactor for the direct starting and stopping of a motor, for starters with forward and reverse directions. There are two electrically and mechanically interlocked contactors so only one is connected to the motor at a time. Star Delta Starters use contactors to reduce the voltage applied to each winding of 3 phase ac induction motors (squirrel cage) to about 58% of the line voltage. This reduces the starting torque and current for a variable amount of time (standard 1-30 seconds) and then switches over to Delta.
