摘要： A molded case circuit breaker is provided with rubber stop assemblies disposed between the contact assemblies adjacent the outside poles and the cover portion of the housing. The rubber stop assemblies are disposed such that they prevent the contact assemblies from damaging the cover. The stop assemblies include a dual purpose U-shaped bracket having two parallel sets of arms. One set of arms is provided with aligned apertures at the free ends for receiving a pin which defines a pivot point for the crossbar assembly. The other set of arms is also provided with aligned apertures at the free end for receiving a metal pin for carrying a cylindrical shock absorber assembly. The shock absorber assembly is mounted adjacent outside poles above the contact carrier but spaced away from the inside of the cover of the circuit breaker. Thus, when the contact arm is opened, it will stop against the shock absorber and not damage the circuit breaker cover. The center pole is provided with an adjacent shock absorber, mounted between a pair of spaced-apart sideplates, vertically disposed and secured to the frame of the circuit breaker. The center pole shock absorber is spaced away from the operating mechanism to prevent the center pole contact assembly from contacting it.

摘要： An electrical circuit interrupter comprising a housing with an operating mechanism disposed therein and including first and second separable main contacts disposed within the housing is taught. There is an electrically conducting first contact support which has a shape which substantially doubles back upon itself and which has parallel, spaced apart first and second legs forming a central region. An electrically insulating support member is supplied which is disposed in the central region and has a substantial portion outboard of the central region in a disposition to shield a portion of the contact support member. It also has a portion which captures the first contact support member. In addition, magnetic plates are disposed within the central region for cooperating with other closed loop magnetic plates outside of the support member for providing a slot motor action for the movable contact. An arc runner is provided which is trapped between the support member and the contact support conductor. All of this is disposed upon a protrusion in the housing of the circuit breaker and held in place by way of a securing device. Lastly, a mandrel is provided for supporting the aforementioned external magnetic plates. The mandrel is gas evolving so that under the influence of the heat of an electrical arc it evolves gas which helps to push the arc out and away from the opening contacts. The aforementioned gas propels the formed arc outwardly away from the contacts in an effort to cool and interrupt the arc.

摘要： A circuit breaker has an electrically conductive blow open latch which forms part of the power circuit so that only short flexible shunts are needed between the latch and trip mechanism. Load current can be conducted from the contact arm to the electrically conductive latch solely through the interface between the latch and the blow open camming surface on the contact arm, and/or through additional short flexible shunts between the latch and the contact arm, preferably adjacent the pivot of the contact arm.

摘要： A molded case circuit breaker is provided with a quick change current transformer assembly. The current transformer is used to sense overcurrent conditions and apply a signal to an electronic trip unit to trip the circuit breaker. The quick change assembly includes an insulated removable plate located adjacent an open cavity in the housing in which the current transformer is located. The current transformer is donut-type disposed about a load-side conductor located in a cavity in the housing rigidly fastened to the circuit breaker frame. In order to replace a current transformer, the insulated backplate is removed. Next the load-side conductor is unfastened and removed from the circuit breaker housing. The current transformer is then removed from the circuit breaker housing. In order to install a new current transformer, the steps are reversed. A force transmitting spacer is disposed adjacent a bight portion of a shunt, connected between a pivotally mounted contact arm and a load-side conductor. The force transmitting spacer transmits magnetic repulsion forces generated between the load-side conductor and the depending leg of the shunt adjacent the load-side conductor to the other depending leg of the shunt. By disposing the force transmitting spacer into the bight portion of the shunt the compression action required between the depending legs of the shunt is eliminated or reduced, thus reducing the blow open time significantly.
摘要翻译：塑壳断路器设有快速变流电流互感器组件。电流互感器用于检测过电流状况，并向电子跳闸单元施加信号以使断路器跳闸。快速更换组件包括位于壳体中的开放空腔附近的绝缘可移除板，电流互感器位于该开口腔中。电流互感器是围绕位于刚性紧固到断路器框架的壳体中的空腔中的负载侧导体的环形型。为了更换电流互感器，绝缘背板被去除。接下来，负载侧导体被松开并从断路器壳体移除。电流互感器然后从断路器外壳上拆下。为了安装新的电流互感器，步骤相反。力传递间隔件邻近分流器的弯曲部分设置，连接在枢转安装的接触臂和负载侧导体之间。力传递间隔件将负载侧导体和分流器的悬臂之间产生的磁力排斥力相邻于负载侧导体传递到分流器的另一个悬臂。通过将力传递间隔件设置在分流器的弯曲部分中，消除或减小分流器的悬垂腿之间所需的压缩作用，从而显着地减少了打开时间。

摘要： A molded case circuit breaker is provided with a toggle assembly having upper toggle links secured to U-shaped members of a cradle assembly with a hardened pin. The pin is formed with annular grooves disposed intermediate the ends forming a center sleeve portion and stop surfaces at each end. The center sleeve portion is slightly longer than the width of the U-shaped member to provide spacing between the upper toggle links and the U-shaped members. The upper toggle links are formed with U-shaped slots disposed at one end which are received in the annular grooves. The U-shaped slots formed at the other end of the toggle links are offset from the longitudinal axis of the toggle links and receive the pin. The upper toggle links are assembled such the offset U-shaped grooves are disposed in opposite directions to help secure the the assembly together. Tolerances in the components will allow a certain amount of axial movement of the upper toggle links and U-shaped members with respect to the pin, which can result in relatively large axial forces on the pin. Since the pin is formed from a hardened metal, the possibility of a failure of the pin is greatly reduced.
摘要翻译：模制外壳断路器设置有肘节组件，其具有固定到具有硬化销的支架组件的U形构件的上肘节连杆。销形成有环形槽，其设置在形成中心套筒部分的端部之间并且在每个端部处停止表面。中心套筒部分比U形构件的宽度稍长，以提供上肘节件和U形构件之间的间隔。上部肘节连接件形成为设置在一端的U形槽，其被容纳在环形槽中。形成在肘节连杆的另一端的U形槽从肘节连杆的纵向轴线偏移并且接收销。上部肘节连接件被组装，使得偏移的U形槽沿相反的方向设置以帮助将组件固定在一起。组件中的公差将允许上肘杆连杆和U形构件相对于销的一定量的轴向移动，这可导致销上相对较大的轴向力。由于销由硬化的金属形成，所以销的故障的可能性大大降低。

摘要： A circuit breaker includes a handle having OFF, ON and intermediate positions, and an extension. A blocking disk has a spring, and first, second and third surfaces. The handle and disk are co-pivotally mounted. The extension engages the third surface for rotation therewith. A pivot lever includes a first end adapted for engagement with a movable contact arm, and a second end adapted for engagement with the first and second surfaces. The first surface blocks the second end as the handle moves from OFF toward the intermediate position, and releases the second end to the second surface at the intermediate position. The first end blocks movement of the movable contact arm when the first surface blocks the second end, and releases the movable contact arm when the first surface releases the second end, thereby moving a movable contact toward a fixed contact in response to the bias of a spring.
