A fusible disconnect switch includes a switch housing, and a first fuse contact member and a second fuse contact member coupled to the switch housing, each of the first fuse contact member and the second fuse contact member configured to engage and complete an electrical connection through an overcurrent protection fuse. The fusible disconnect switch further includes a switch contact including a parallel contact configuration. An interlock is operatively coupled to the first fuse contact member and a switch that operates the switch contact, the interlock configured to inhibit movement of the switch from the OFF position to the ON position when the first fuse contact member is unsecured to the switch housing, and inhibit movement of the first fuse contact member relative to the switch housing when the switch is in the ON position.

An embodiment of an outdoor unit of a climate control system includes a refrigerant compressor, an electric motor configured to drive the refrigerant compressor, and a variable frequency drive (VFD) electrically coupled to the electric motor and configured to be electrically coupled to a ground-fault circuit interrupter (GFCI). The GFCI is electrically couped to an electrical power source. The VFD has circuitry that includes an electromagnetic interference (EMI) filter configured to at least partially filter electromagnetic interference generated by the VFD, and an inductive device that is configured to be electrically coupled to the GFCI in parallel with the EMI filter. The inductive device is configured to at least partially dissipate current discharged from the EMI filter in response to a de-energization of the electrical power source, to thereby prevent a trip of the GFCI upon re-energization of the electrical power source.
