摘要： A circuit breaker includes a latch including a switching mechanism for opening and closing a switching contact operatively connected to a tensioning element, and an unlatching mechanism by which, on the basis of a tripping signal, the tensioning element can be changed from a tensioned to an at least largely untensioned state, thereby opening the switching contact. In an embodiment, the tensioning element is indirectly linked to a tensioning lever having a locating surface on which a locking pawl of the unlatching mechanism bears in the tensioned state of the tensioning element. The locating surface is curved in the direction of the locking pawl and is movably disposed relative to the tensioning lever.

摘要： A switching device for the interruption of a fault current includes a housing having first and second electrical connectors for connection in the path of an electrical conductor carrying a single current phase. A vacuum switching chamber is disposed in the housing. A current transformer disposed in the housing includes a primary circuit connected between the first and second terminals for conducting the single current phase and inducing a corresponding current in a secondary winding. A magnet actuator disposed in the housing is electrically coupled to the transformer secondary winding. The magnet actuator is responsive to a fault current in the transformer primary, by way of the corresponding current in the secondary, for changing from an inactive state to an actuated state. A latch disposed in the housing is connected for latching the movable switch contact in a closed position and for being unlatched in response to a change to the actuated state of the magnet actuator for moving the movable switch contact to an open position. A turn-off spring causes the latch to move the movable switch contact away from the stationary switch contact when the latch becomes unlatched.
