ABSTRACT:
An electric switch has a first molding for supporting an isolation switch and at least one line side power fuse clip, where the line fuse clip is capable of retaining a first end of a power fuse fed by the isolation switch. A second molding for supporting at least one load side power fuse clip is provided, where the load fuse clip is capable of retaining a second end of the power fuse. At least one projection is formed into the second molding for supporting a control circuit fuse, where the projection is substantially parallel to and beside an installed power fuse, and a control circuit line side fuse clip and a corresponding load side clip is mounted to each of the projections formed into the second molding, so that installed control and power fuses are spaced apart and substantially parallel. A conductor behind a terminal of the power fuse connects the load side power fuse clip to the control circuit line side fuse clip. A socket may be formed in a top surface of the first molding, and the line side power fuse clip may be attached to a lower surface of the first molding, so that a bus bar may be supported above the first molding. The isolation switch may control a three phase line. Projections are molded into the first molding in order to provide insulation between conductive compartments for each phase.
