Abstract: A fin for a heat exchanger that includes a fin body formed from a sheet of material; a plurality of openings formed in the fin body, each of the plurality of openings having a pair of rounded end portions connected by an elongated central portion; and at least one stand-off attached to the fin body along the elongated central portion of the opening, wherein the at least one stand-off includes a leg having a proximal end connected to and that extends outward from the fin body and a distal end, and the at least one stand-off includes a footing connected to the distal end of the leg that extends outward from the distal end in a direction away from the central portion of the opening.

Abstract: A fuse holder provides a safe device for connecting fuses to a three-phase busbar device. Each phase includes a corresponding load conductor and line conductor mounted within a housing. A mechanical lock is provided for each phase that locks a knife of the fuse to one of the conductors for the phase. In a further aspect, the fuse knives are frictionally locked within the housing. In both the mechanical lock and frictional lock, a release mechanism is provided that can be activated by a screwdriver to release the fuse knives from the fuse holder. In another aspect, certain conductors are provided with heat dissipation wings that contact the housing to dissipate heat generated by current flowing through the conductor.
