摘要： An electrical switchgear comprises a front, a back and a switch arrangement. The switch arrangement comprises a terminal arrangement comprising an electrical contact for a bus and an electrical contact for a load connection which are spaced apart along an axial direction; and a device that is driveable into said terminal arrangement to a service position to make an electrical connection between said electrical contact for said load connection and said electrical connection for said bus. The electrical contact for said load connection is located closer to said back of said switchgear than is said electrical contact for said bus.

摘要： Heat sinks extending rearward from and connected to the risers of a switchgear assembly by the same fasteners which secure the stabs to the risers dissipate the joule heat generated by current flow through the risers and stabs and accommodate for the higher temperature rise permitted in the power circuit breakers engaged by the stabs. The heat sinks are formed by a pair of heat sink members straddling the risers, each of which has an elongated flat body with an extended flat mounting surface on a first face which provides extended surface engagement with a stab. The elongated body projects rearward beyond the stab and a first set of transverse fins project from the first face rearward of the stab toward the first set of fins on the other heat sink member of the pair. A second or additional set of fins project laterally outward from a second face opposite the first face of the elongated body and are dimensioned to maintain appropriate through-air clearance with the additional fins on the heat sinks on an adjacent riser.

摘要： An enclosure for drawout circuit interrupters having instrumentation and control wiring includes a housing having circuit interrupter recesses; wiring tray recesses; wiring trays each of which hold the wiring for one of the circuit interrupters; drawout mechanisms for removing the trays from the tray recesses; and brackets for hanging the trays from the enclosure. The trays may have a molded plastic front panel. The trays may also have internal lances or holes for securing the wiring thereto, two rear holes for routing the wiring therethrough, and a bottom side having holes for mounting rails for securing terminal blocks or fuse blocks thereto. The rear holes may hold peripheral plastic conduits for protecting the wiring. The front panel may have recess pockets for holding a descriptive nameplate, and center punches to facilitate mounting instrumentation or control devices. The drawout mechanisms may have a rectangular guide bar beneath the trays. Each tray may have a corresponding guide mechanism which rests on the guide bar. The guide mechanism may have two arms each of which abut a side of the corresponding guide bar. The drawout mechanisms may further have H-shaped slide bars attached to the sides of the trays and L-shaped brackets attached to the housing within the tray recesses. Each of the L-shaped brackets may have a C-shaped channel for guiding one of the slide bars. The drawout mechanisms may also have blocking tabs for partially blocking a drawout movement of the trays from the tray recesses.
