The Spring Operating Conventional Mechanism consists of:

  • A spring charging unit which can be charged manually or electrically by a geared motor.
  • Mechanical indicator showing spring charged/discharged condition.
  • Indicator for open/close position of the circuit breaker.
  • Closing/tripping solenoids for performing closing/opening operation of the circuit breaker electrically.
  • The NC contact of the cut-off switch is opened whenever the spring gets charged and interrupting the motor circuit.
  • Over charging protection is enabled, i.e., If the cut-off gets failure, there is no issue to Motor.
  • The closing and opening operations can be carried out by means of the energy stored in the operating mechanism. Double Spiral spring is used to carry out the closing and opening operation of the breaker
