  • Patent number: 10580608
    Abstract: A breaker mechanism for an electrical circuit breaker is disclosed, the breaker mechanism including a spring, a latching mechanism and an actuating element, with which a breaker shaft of the electrical circuit breaker is actuated for breaking (OFF position) or making (ON position) the electric current. In an embodiment, the actuating element is actuated in the direction of the ON position when making the electric current, and the spring is thereby tensioned. Further, the latching mechanism releases the energy of the spring for actuating the breaker shaft of the electrical circuit breaker when the ON position is reached.

  • Patent number: 9275805
    Abstract: A switching unit for an electrical switching device, in particular an electrical circuit breaker, is disclosed. The switching unit includes a switching lock with a switching mechanism and a rotor housing with a contact arm disposed therein for opening and closing contacts during a rotation of the rotor housing about a rotation axis. In an embodiment, at least one lever apparatus is functionally connected at its upper end by way of the switching mechanism and at its lower end by way of a connecting pin to a face of the rotor housing.

  • Patent number: 9230767
    Abstract: A blocking element is disclosed for blocking the movement of a handle or a switching lever of an electrical switch. In at least one embodiment, the blocking element is switchable between at least two positions. In the first position, the blocking element can block the movement of the handle or of the switching lever and, in the second position, the blocking element cannot block the movement of the handle or of the switching lever.

  • Patent number: 9171684
    Abstract: A circuit breaker includes a latching mechanism including a switching mechanism operatively connected to a tensioning element, and an unlatching mechanism by which, in response to a tripping signal, the tensioning element can be transferred from a tensioned state into an at least substantially relaxed state. The tensioning element is indirectly coupled to a tension lever which can be locked or tripped 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 despite a tripping signal. The blocking mechanism of the tension lever includes a rocker arm which is fastened movably on the tension lever.

  • Patent number: 9165730
    Abstract: A switching apparatus for an electric switch, in particular an electric circuit breaker, including a switching head with a grip section, and a switching frame connected to the switching head. In an embodiment, a bearing end of at least one spring element is mounted on the switching frame on at least one bearing device. The switching head for the bearing end of at least one spring element includes at least one positioning depression on the side of the switching head opposite to the grip section, which is embodied for a lateral positioning of the bearing end.

  • Patent number: 9111695
    Abstract: An electrical switching device includes a switching mechanism, a housing element, a cover element and a test button, which is movable between a non-actuated position and an actuated position. When the test button is moved from the non-actuated position into the actuated position, the switching mechanism disconnects at least one moveable contact from at least one fixed contact of the switching mechanism. Further, a blocking element is movable between a first position and a second position, so that the blocking element, when the cover element is closed, is held by the cover element in the first position against a pre-tensioning force in the direction of the second position. Further, when the cover element is opened, the blocking element moves the test button from the non-actuated position into the actuated position.

  • Patent number: 9099259
    Abstract: 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.
