摘要： A molded case circuit breaker is provided with a two piece cradle assembly having a cradle portion and a heat-treated portion. The heat-treated portion forms the latch and reset surfaces. The cradle portion is integrally formed from a pair of spaced apart cradle-shaped arms joined together by a connecting portion. The heat treated portion is securely fastened to the connecting portion to form the two piece cradle assembly. A hold down slidably carries a handle barrier with respect to the cover and closes a centrally located aperture in the cover for all handle positions. The handle barrier prevents arc products resulting from a separation of the main contacts from escaping through the centrally located aperture in the cover. Stops are provided in one or both directions to prevent misalignment of the handle barrier with respect to the operating handle. A cover interlock is also provided to prevent the cover from being removed when the circuit breaker is in an "on" position. The cover interlock can either be molded separately or integrallly molded with the handle barrier hold down.
摘要翻译：模制外壳断路器设置有具有支架部分和热处理部分的两件式支架组件。热处理部分形成闩锁和复位表面。托架部分由连接部分连接在一起的一对间隔开的支架形臂整体形成。热处理部分牢固地固定在连接部分上以形成两件式支架组件。一个按扣可滑动地携带相对于盖子的手柄屏障，并关闭盖子中心定位的孔，用于所有手柄位置。手柄屏障防止由主触头分离而导致的电弧产物逸出通过盖中心定位的孔。止动件设置在一个或两个方向上以防止手柄屏障相对于操作手柄的不对准。还提供盖互锁以防止当断路器处于“打开”位置时盖不被移除。盖子互锁可以单独模制，也可以与手柄屏障按压一体成型。

摘要： An improved lockable fastener that can be employed in a circuit breaker application includes a first member and a second member that are threadably cooperable with one another and a locking member that extends between the first and second members to resist loosening of the first and second members. The second member includes a threaded shank that is threadably received in a first threaded portion of a cavity formed in the first member. The locking member includes a threaded body and a taper, with the threaded body being threadably receivable in a second threaded portion of the first member, and with the taper being at least partially receivable in a receptacle formed in the shank of the second member. The receptacle defines a seat on the shank, and the taper engages the seat to deform at least a portion of the shank into engagement with a ledge that is interposed between the first and second threaded portions of the cavity.

摘要： Rectangular bus bars alternatively engaged in either of a pair of crossed slots in a support block secured in a panel board are locked in place by a locking device incorporated in a cylindrical terminal portion of each bus bar. The locking device includes an expandable ring seated in a circumferential groove in the cylindrical terminal portion. A pair of actuating pins are urged radially outward in diametrically opposed bores to wedge the expandable ring against the support block, by a tapered screw threaded into a central longitudinal bore in the terminal portion of the bus bar.

摘要： A locking device is insertable into a cover opening adjacent to a handle of an electrical switch to occupy the space in the cover opening for resisting movement of the handle. The locking device has two pivotally connected members. The pivotal movement of the members creates a collapsed condition or an expanded condition for the locking device. The pivotal members have a transverse opening which are alignable relative to each other when the locking device is in its expanded condition. The locking device is inserted into the cover opening when the pivotal members are collapsed. In a first embodiment, a handle shroud member has an opening for receiving the handle and a second member has leg means along its base for engaging an undersurface around the cover opening when the locking device is in its expanded condition. In a second and a third embodiment, both pivotal members have leg means for engaging undersurfaces around the cover opening when the locking device is in its expanded condition. Once the apertures of the members are in alignment, a padlock is inserted therethrough for retaining the locking device in its expanded condition in the cover opening thereby resisting movement of the handle of the electrical switch.

摘要： A circuit breaker includes a housing and an operating mechanism having a cross bar supported by a first housing surface and moving in an arcuate path between open/tripped and closed positions, a pivotally mounted cradle including a latch, and pivotally mounted primary and secondary latches. The primary latch includes a pivot, an opening and a free end. The cradle latch rests within the opening when the contacts are not tripped open. The secondary latch includes a pivot and a surface. The latches are between a second housing surface and the cross bar in a first position. The cross bar is offset from the latches in a second position. The secondary latch surface and pivot are between the second housing surface and the primary latch pivot. The secondary latch surface engages the primary latch free end when the contacts are not tripped open and maintain the cradle latch within the opening.

摘要： A lockable fastener connects together a plurality of components of a circuit breaker and maintains electrical conductivity between the components while permitting relative movement therebetween. The lockable fastener includes a first clinch nut member and a second clinch bolt member. The clinch nut member includes a threaded cavity formed therein, a side having opening therein, and a passageway between the side at the opening and a surface proximate the threaded cavity. The clinch bolt member includes a threaded shank. At least a portion of the threaded shank is threadably receivable in the threaded cavity of the clinch nut member, in order to axially align the clinch nut and clinch bolt members. The clinch nut and clinch bolt members are adapted to be locked by deformation of the surface of the clinch nut member to prevent loosening of the members.

摘要： A molded case circuit breaker includes an interlock which prevents the operating handle from being moved from the on position after the main contacts have been welded together. By preventing the operating handle from being moved from the on position during such a condition, the operating handle will indicate the correct status of the main contacts and the operator will be made aware that the main contacts are welded together.
