  • Latching operating mechanism of a three-position circuit breaker
    Patent number: 4821008
    Abstract: A latching mechanism comprises an energy storage system having a first closing spring, and a second opening and earthing spring, arranged between a transmission device and a closing control crankshaft and an earthing crank. A retaining plate pivoting on an axis cooperates on the one hand with an opening control lock by means of a unidirectional locking and on the other hand with the crankshaft by means of two latchings. The first latching is released during the opening travel after the lock has been unlocked, and the second latching causes positive locking of the device at the beginning of the closing travel of the crankshaft.
