Abstract
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.
