Working Mechanism

  • The mechanical interlocks have a stationary housing with a movable latch connected to the control circuit of the motor starter.
  • After the motor starter is switched off, the latch remains in the locked position to prevent the load from opening or closing.
  • After the motor starter is switched on, the latch gets released to allow the load to open or close based on the motor rotation direction.
  • If the load is opened during the operation of the motor, the latch gets locked to stop the motor & prevent further damage to the equipment.
  • When the motor starter is switched off, the latch locks the load again to prevent the load from opening or closing.
