Abstract: A remote controlled miniature circuit breaker includes a helical gear that engages with mating teeth of a slider plate coupled to main contacts of the circuit breaker, the helical gear including a flat portion to allow the sliding plate to slide past the helical gear. A unidirectional motor responds to an external signal to drive the helical gear while engaging the mating teeth of the slider plate, thereby moving the slider plate to close the main contacts. The motor is configured to respond to an external signal to resume the unidirectional rotation of the helical gear to position the flat portion of the gear to allow the slider plate to slide past the helical gear and contact a kicker lever to thereby open the main contacts. A trip lever pivotally mounted separately from the kicker lever, pushes the kicker lever to open the main contacts in a trip operation.
