Abstract:
1. A circuit breaker, comprising: a latching mechanism including a switching mechanism for opening and closing a switch contact which is operatively connected to a tensioning element; and an unlatching mechanism by which, in response to a tripping signal, the tensioning element is transferrable from a tensioned state into an at least substantially relaxed state in such a way that the switch contact is opened thereby, the tensioning element being indirectly coupled to a tension lever which is lockable or trippable as a function of a position of a blocking pawl of the unlatching mechanism and which includes a blocking mechanism by which, in an OFF position of the latching mechanism, in which the switch is open and the tensioning element is tensioned, tripping of the tension lever is prevented, the blocking mechanism of the tension lever including a rocker arm fastened movably on the tension lever, wherein, upon being transferred into the OFF position, the rocker arm is movable together with the tension lever such that the blocking pawl is removed from a stopping face of the tension lever.
