Document Type and Number:
Japanese Patent JPS63500906
Kind Code:
A
Abstract:
An electric circuit breaker capable of being opened and closed from a remote location. The circuit breaker includes a stationary contact, a movable contact mounted on a carrier and a trip mechanism that trips the circuit breaker, moving the carrier to an open position upon the occurrence of an overcurrent. The remote control assembly opens and closes the circuit breaker independently of the trip mechanism. Upon receiving a signal from a timer switch, a motor operates, rotating a gear spring connected to the motor shaft. An actuator has a tooth positioned between the wire layers of the gear spring. As the gear spring rotates, the tooth moves toward the motor, pivoting the actuator. An operating rod, connected to both the actuator and the carrier, pulls the carrier to open the contacts as the actuator rotates. When the contacts reach the open position, the actuator hits a switch to shut off the motor.
