  • Remote control system circuit breaker
    Patent number: 4529951
    Abstract: A remote control system circuit breaker which latches a trip link and a latch link by the spring force of return springs so that on- or off-hold of a movable contactor supported from the latch link depends upon a holding force of an operating electromagnet pivotally connected to a handle, thereby achieving miniaturization of the electromagnet, in turn the circuit breaker, and a saving of power consumption of the electromagnet.
