LATCHING DEVICE FOR A CIRCUIT BREAKER

摘要

Latching device for a circuit breaker comprising - a manual operating toggle (2) which is moveable arranged between an OFF-position and an operation-readiness position, - a moveable contact (52) and a fixed contact (51), wherein the moveable contact (52) is adapted to open and close the main circuit of the circuit breaker, - an energy storage mechanism which stores an actuating force of the toggle (2) when the toggle (2) is moved from the OFF-position to the operation-readiness position and is adapted to exert the stored force to the moveable contact (52) to close the main circuit of the circuit breaker, characterized in that the latching device further comprises a removable retention lever (4) for preventing the movement of the moveable contact (52) into a closing position if the energy storage mechanism exerts the stored force to the moveable contact (52).
