    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 circuit breaker having an automatic release linkage is disclosed that is capable of preventing damage and deformation of elements by automatic linkage release before electro-impulsive force generated from within the circuit breaker by a large short-circuit current causes the damage and deformation of open/close linkage.

    摘要： A ball actuator 10 comprises a case 12 supporting a striker 14 with an energy storage spring 16, a control rod 18 movable in translation in a direction parallel to a geometric axis 19, detent balls 20 and control balls 22. When the rod is moved in translation by an electromagnetic relay 100, the control balls 22 escape and enable the detent balls 20 to be freed so that the striker 14 is released. Each control ball 22 is in contact with two detent balls 20 and with the rod 18 so that the forces applied to the rod 18 by the control balls 20 are much lower than the forces exerted by the striker 14 on the detent balls 22. A high-efficiency actuator is thus achieved requiring a low operating energy and with small overall dimensions.

    摘要： A switching accessory is provided for use with motor starters. In a first embodiment the accessory may be utilized as a motor starter by-pass. In another embodiment the accessory may be utilized as a motor starter isolator. The switching accessory utilizes lever action and fulcrum points to open and close contacts as desired. More particularly, the switching accessory includes a pull bar contactor arrangement, an actuator mechanism, a fulcrum shaft and an operator lever. The pull bar contactor arrangement may be axially displaceable between pairs of bus bars to permit electrical connections between the bus bars of each pair. The pull bar may be movable between a first position in which the contacts of the bus bars of each pair are isolated from one another and a second position in which the contacts of the bus bars of each pair are in electrical contact via contact elements on the pull bar. The actuator mechanism may be motor driven for linearly displacing an actuator member between predetermined limit positions. The fulcrum shaft is axially displaceable between two predetermined limit positions. The operating lever is pivotally connected to the pull bar, the actuator member of the actuator mechanism and the fulcrum shaft. The arrangement of the pull bar, the actuator mechanism, the fulcrum shaft and the operating lever may be such that, with predetermined biasing forces of biasing means acting on the fulcrum shaft and the pull bar, the operation of the actuator mechanism creates the desired electrical connection through a series of movements of the components of the accessory.

    摘要： A circuit breaker comprises a stored-energy mechanism and a resettable roller-type latch for latching the stored-energy mechanism. The latch is operable upon the occurrence of overload current conditions to release the stored-energy mechanism to thereby trip the breaker. Alternately the latch may be actuated by utilizing a separate switch.
