摘要： A circuit breaker operating mechanism for separating a pair of electrical contacts within an electrical circuit breaker includes a lower link operatively connected to one of the electrical contacts. An upper link includes first and second legs extending from a central portion. The first leg is pivotally secured to the lower link, and the second leg includes a cam surface formed thereon. A roller is in intimate contact with the cam surface, and the cam surface is configured such that movement of the upper link relative to the roller causes the upper link to pivot about the central portion. Pivoting of the upper link about the central portion moves the lower link causing the second contact to move away from the first contact. An operating spring is configured to provide a force for separating the electrical contacts when the operating mechanism is tripped. An operating handle includes a void disposed therein, and an end of the spring is secured to the operating handle within the void.

The termination connector preferably includes a plurality of single pole screw receiving members integrally attached by a molded housing for unitary attachment to a line or load end of a circuit breaker to assist in holding a nut or nut plate adjacent each screw hole in the circuit breaker's terminal straps. The molded housing preferably includes a line of perforations between each single pole screw receiving member so that the correct number of single pole screw receiving members can be retained and the others can be knocked off along the line of perforations. Provisions are disclosed for adaption of the connector to metric or English standard nut hardware. In addition, the termination connector and circuit breaker are provided with mating attachment devices for providing a simple yet secure connection.

摘要： A trip actuator (66) includes a trip spring (106) to bias the trip arm (104) in a clockwise direction about trip arm pivot (120). In the latched and ready to operate state, the clockwise moment about the axis of the latch pivot (132) created by force “F” opposes the counterclockwise moment created about the axis of the latch pivot (132) created by the horizontal component “fx” of force “f”, to hold the latch (110) in the upright position against the force of the trip arm (104). When a trip (triggering) signal is provided to the flux shifter (102), the flux shifter (102) releases the plunger (130). With the force “F” removed, the trip arm (104) will drive the latch pin (134), causing the latch (110) to rotate counterclockwise about the latch pivot (132). As the latch (110) and trip arm (104) rotate, the latch pin (134) slides off the latch surface (126), fully releasing the trip arm (104) and allowing the trip paddle (96) to move the secondary latch tab (50).
摘要翻译：跳闸致动器（66）包括跳闸弹簧（106），以围绕跳闸臂枢轴（120）沿顺时针方向偏置跳闸臂（104）。在锁定和准备操作状态下，围绕由“F”形成的闩锁枢轴（132）的轴线的顺时针方向与由水平分量“fx”产生的锁定枢轴（132）的轴线产生的逆时针方向相反的力“f”，以克服脱扣臂（104）的力将闩锁（110）保持在直立位置。当向通量变换器（102）提供跳闸（触发）信号时，通量变换器（102）释放柱塞（130）。在力“F”被去除的情况下，跳闸臂（104）将驱动闩锁销（134），使得闩锁（110）围绕闩锁枢轴（132）逆时针旋转。当闩锁（110）和跳闸臂（104）旋转时，闩锁销（134）从闩锁表面（126）滑出，完全释放跳闸臂（104），并允许跳闸桨（96）移动辅助闩锁标签（50）。

摘要： A circuit breaker operating mechanism comprises a movable handle yoke, a mechanism spring extending in tension from the handle yoke to a pin, and a lower link extending from the pin to a crank operably connected to a contact arm bearing a movable contact. The crank is positionable in open and closed positions, being in an open position when the movable contact is separated from an associated fixed contact and being in a closed position when the movable contact is mated to said associated fixed contact. The circuit breaker further comprises an interface formed on said crank and a blocking prop having a first surface that engages said interface, the first surface preventing the crank from rotating towards the closed position.

摘要： A return spring mechanism is arranged to operate with a circuit breaker operating mechanism during a trip condition. The circuit breaker operating mechanism is movable between a tripped position, a reset position, an off position and an on position. The return spring mechanism is attached to the exterior of the circuit breaker frame and includes a return spring with a fixed end attached to the frame. When the circuit breaker is tripped, the return spring mechanism operates to provide an additional force to the handle yoke. The additional force applied by the return spring is predetermined to position the handle yoke intermediate to the handle yoke positions when the circuit breaker is off and on. Thus, the movement of the handle yoke to the intermediate position provides clear indication that the circuit breaker is in the tripped condition.
