摘要： A combination panelboard-switchboard housing accepts plug-on connection with a plurality of modular electric switch-circuit breaker enclosures. The modular enclosure accepts circuit breakers or electric switches which can be field-installed with minor alteration to the enclosure. The modular switch enclosure further accepts a wide range of ampere ratings within a standard enclosure size. A mechanical latch arrangement on the bottom of the modular enclosure prevents the modular enclosure from being removed from the panelboard-switchboard housing. Controlled temperatures are achieved within the housing by optimized circulating air flow.

摘要： A compact electric safety switch including a rotatably mounted double contact assembly. Heavy duty compression springs are positioned under the blade assembly for rapid make and break connection between a pair of contact stabs. The series arrangement between the pair of contact stabs generates a corresponding pair of electrical arcs during the make and break occurrence which is less intense and of shorter duration than standard single contact arrangements. The pair of less intense arcs of short duration allow for a corresponding pair of arc chutes of smaller size than standard single arc chute arrangements. The contact stabs that receive the double contact blade are staggered to reduce electromagnetic attraction between the contact and the stabs.
摘要翻译： 一种紧凑型电气安全开关，包括可旋转安装的双接触组件。 重型压缩弹簧位于刀片组件下方，用于快速断开和断开一对触点之间的连接。 一对接触片之间的串联布置在制造和断裂发生期间产生相应的一对电弧，其比标准单个接触装置更不强烈且持续时间更短。 一小撮较短时间的弧线允许与标准单弧槽排列相对应的一对较小尺寸的相应的弧槽。 接收双接触刀片的触点突起交错，以减少触点和刺针之间的电磁吸引力。

摘要： In a circuit breaker load center there is provided a main lug assembly constructed for interchangeable installation with a main circuit breaker. The lug assembly comprises an insulative mounting block to which are secured a pair of conductive straps in closely spaced parallel relation. An upstanding barrier wall integral with the block provides electrical isolation between the straps, as well as between wire connector lugs affixed in electrical connection to one end portion of each strap. The block is notched to expose the other terminal end portion of each strap for electrical connection to terminal ends of the load center busbars.

摘要： A multiple metering panelboard has an enclosure accommodating a plurality of watt-hour meter sections. Each section includes a molded plastic meter socket base and a molded plastic circuit breaker base mounted in interconnected relation to the enclosure in overlying relation to an array of busbars common to all meter sections of the assembly. The socket base of each section includes means for positioning at appropriate locations within the meter socket a plurality of jaws which are supported against meter insertion forces by rigid straps respectively electrically connecting the jaws to the underlying busbars and to circuit breaker line stabs mounted by the breaker base.

摘要： A molded case circuit breaker plastic support saddle includes means integrally formed therein for supporting the main bus conductors along with neutral conductors. The neutral conductors are arranged as a pair of conductors parallel with and outboard of the main bus conductors. Interconnection between the neutral conductors is made by a C-shaped insulated metal crossarm contained within a two-part insulating casing. This arrangement of the main bus conductors and neutral conductors allows for robotic assembly in a high speed manufacturing process.
