Abstract:
A plug-in switchgear apparatus comprising: a fixed frame; a circuit breaker movable in the fixed frame between a plugged-out position and a plugged-in position, the circuit breaker comprising at least one pair of contacts at least one of which is movable with respect to the other between a closed position and an open position; a loading and closing mechanism, comprising a closing spring movable from a loaded state to a released state, the closing spring being associated to the movable contact so that relaxation of the closed spring drives the movable contact to the movable contact's closed position, a closing latch for latching the closing spring, in the closing spring's loaded state, a drive mechanism comprising a drive part, a coupling mechanism between the drive part and the closing spring, said coupling mechanism being movable from a coupling state in which actuation of the drive part moves the closing spring to the closing spring's loaded state, to an uncoupling state in which actuation of the drive part does not move the closing spring to the closing spring's loaded state.
