Abstract
The locking device of a plug-in and disconnection mechanism for a circuit breaker comprising a kinematic transmission system driven by a removable crank comprises a main locking catch able to take a closed position in which it prevents the crank from being fitted and an open position in which it enables the crank to be fitted, at least one operating cam and lever mechanism designed to take information representative of one or more positions of the circuit breaker and to prevent passage of the mobile element of the main locking catch to its closed position when none of these positions is detected, and an operating mode selector. In the embodiment with one cam and lever mechanism, the selector enables the cam and lever mechanism to be activated or neutralized. In the embodiment with two cam and lever mechanisms, the selector enables one or the other of the two cam and lever mechanism to be selected.
