摘要： A circuit breaker having a magnetic trip assembly includes a load terminal conductor having a first section, a second section, and a transition section connecting the first section and the second section, the transition section having a pair of faces lying in a plane generally perpendicular to a surface of the second section; a current transformer positioned around the second section of the load terminal conductor, the current transformer having a first side positioned generally parallel to the faces of transition section; and an insulating barrier positioned between the first side of the current transformer and the faces of the transition section of the load terminal conductor, the insulating barrier having a generally planar portion and a pair of leg portions extending from one edge of the generally planar portion, each leg portion lying along a side of the second section of the load terminal conductor and having a protrusion positioned adjacent a distal end thereof, each of said protrusions being positioned adjacent a bottom edge of the second section of the load terminal conductor. Insulating barriers for use in such circuit breakers are also included.

摘要： The secondary cover of a molded case power switch housing is removably secured in place to enclose cavities in the insulative resin of a primary cover by an attachment assembly which includes metal attachment members or inserts seated in recesses in the primary cover. These inserts have tapped apertures aligned with mounting holes in the secondary cover through which screw fasteners are inserted and threaded into the tapped apertures. Such metal to metal connections can be repeatedly coupled and decoupled without significant wear as the secondary cover is removed and reinstalled to gain access to auxiliary devices mounted in the cavities in the primary cover. The inserts have second mounting apertures through which self tapping screws extend into the primary cover or through mounting holes in the primary cover and into the resin of the base to mount the inserts on the primary cover and to secure the primary cover to the base.

摘要翻译： 模制外壳电源开关壳体的辅助盖可移除地固定在适当位置，以通过附接组件包围主盖的绝缘树脂中的空腔，所述附接组件包括位于主盖中的凹部中的金属附接构件或插入件。 这些插入件具有与第二盖中的安装孔对准的孔，其中螺钉紧固件通过该孔插入并拧入到螺纹孔中。 这样的金属对金属连接可以重复地耦合和去耦合，而不会有明显的磨损，因为二次盖被去除并重新安装以进入安装在主盖中的空腔中的辅助装置。 插入件具有第二安装孔，自攻螺钉通过该第二安装孔延伸到主盖中或通过主盖中的安装孔进入基座的树脂中，以将插入件安装在主盖上并将主盖固定到基座上。
