1. A fuse cutout assembly comprising:
a cutout body,
wherein the cutout body includes a first contact, a second contact, and an insulator;
an upper adapter configured for releasable coupling to the cutout body;
a lower adapter configured to be pivotally coupled to the cutout body,
wherein the lower adapter includes a notch in a wall of the lower adapter;
and
a fuse assembly,
wherein the fuse assembly comprises:
a first end cap configured to be securely positioned within an interior area of the lower adapter;
a second end cap configured to be securely attached to the upper adapter;
a casing positioned between the first end cap and the second end cap, the first end cap and the second end cap each being an electrical contact that is electrically coupled to a fuse element, the fuse element being housed at least within an interior region of the casing; and
a displaceable pin assembly,
wherein at least a portion of the displaceable pin assembly being secured within the first end cap,
the displaceable pin assembly including:
a plunger that is selectively displaceable along an axis that is non-parallel to a central longitudinal axis of the fuse assembly,
the plunger being selectively displaceable between an extended position at which at least a first end of the plunger is outwardly positioned away from an outer surface of the first end cap, and
a recessed position at which the first end of the plunger is recessed within the first end cap or is generally aligned with the outer surface of the first end cap, the plunger being configured to be received in the notch of the lower adapter when the first end cap is positioned in the interior area of the lower adapter and the plunger is aligned with the notch and at the extended position,
wherein the notch and the plunger are positioned to, when the plunger is received in the notch, orient the fuse assembly at a predetermined rotational and linear alignment relative to at least the lower adapter.
