    摘要: A compact electric safety switch including a rotatably mounted double contact blade assembly. Heavy duty compression springs are positioned under the blade assembly for rapid make and break connection between opposing line and load contact stabs. A pair of contact springs directs the contact blade during transit between the line and load contact stabs and serves to increase the contact pressure between the contact blade and the contact stabs when the contact blade is inserted therein.

    摘要: A Fusible electric switch is herein described for increased ratings within industrial electrical distribution circuits by the provision of an arc exhaust gas controller. The arc gas controller cools and deionizes the arc gases that are generated upon separation of the switch contacts and exhausts the gases in a predetermined direction outside the switch enclosure. Fuse pullers are arranged at one end of each of the switch fuses to facilitate both installation and removal of the fuses.

    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 circuit breaker support saddle is assembled automatically from three plastic support pieces without welding or using separate fasteners to secure the pieces together. The metal circuit breaker support rails are positioned onto blocks integrally formed on the two outermost pieces to mechanically hold the pieces together as a single unit. The circuit breaker stab support busses are retained within elongated slots formed within the outer edges of the central support piece.

    摘要: A combination panelboard-switchboard housing accepts plug-on connection with a plurality of electric switch-circuit breaker modules. Circuit breakers can also be directly connected onto the bus bars in a plug-on connection with minor modification. The bus bars are "edge-mounted" such that the minor dimension of the bus bars is perpendicular to the bottom of the housing to receive the modules as well as the circuit breakers, per se. Electrical insulation shields are arranged over those bus bars that are not connected with the circuit breakers or modules to prevent inadvertent contact with the bus bars when energized. The tabs extending from the edge of the insulation shields are keyed to accommodate for the different widths of the modules when the insulation shields are flush-mounted against one side of the modules.

    摘要: A multi-component electric switch-circuit breaker module permits electric switches and circuit breakers to be field-installed within existing panelboard-switchboard enclosures. The module contains a pair of compartments that are accessed by separate doors. Electric switches or circuit breakers can be arranged within both compartments or an electric switch can be installed within one compartment with an electric circuit breaker installed within the other. The module is removably attached to the panelboard-switchboard interior by means of a bail handle arrangement. The module is removed from the assembly by unscrewing the bail handle and manually accessing the module. Spring-loaded connector clips allow for repeated connection with and disconnection from the systems power bus with minimum contact resistance.

    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.
