Abstract: A switchgear includes a housing having first and second side walls and at least one shelf member. The at least one shelf member includes a guide element. A withdrawable switchgear unit is slidingly supported on the at least one shelf member. A blocking mechanism is mounted to the withdrawable switchgear unit. The blocking mechanism includes a guide pin arranged in the guide element and a blocking pin operatively connected to the guide pin. The blocking pin selectively restricts movement of the withdrawable switchgear unit between at least two operational positions.

Abstract: A door hinge includes a hinge body, a hinge pin, and a hinge base. The hinge body includes a first channel that defines a first axis, the hinge body further includes a slot formed therethrough at an angle to the first axis, and the hinge body further includes a retention apparatus arranged within the slot. The hinge pin is operatively disposed in the first channel and configured to travel along the first axis, the hinge pin includes at least three retention formations formed thereon, a first retention formation defines a first retention position, a second retention formation defines a second retention position, a third retention formation defines a third retention position, and the retention apparatus is configured to engage the hinge pin at one of the at least three retention formations. The hinge base includes a second channel configured to operatively receive at least a portion of the hinge pin.

Abstract: A frame for an enclosure includes a first set of corner support structures. Each corner support structure of the first set of corner support structures includes a main body, a first protrusion arranged to extend from the main body, a second protrusion arranged to extend from the main body and substantially orthogonal to the first protrusion, and a third protrusion arranged to extend from the main body and substantially orthogonal to both the first protrusion and the second protrusion. The frame further includes a second set of corner support structures having mirror image symmetry about a plane of symmetry of an opposing corner support structure of the first set of corner support structures.
