An electrically insulative case for an electrical device includes a housing defining an interior space. The electrically insulative case also includes a frame operatively coupleable to the housing in a plurality of orientations. The frame defines at least one opening that provides access to the electrical device. An inner sidewall of the frame extends into the interior space. The electrically insulative case further includes a restrictor coupleable to the electrical device such that the restrictor extends adjacent to the frame. The restrictor is arranged to inhibit objects from moving from an exterior of said housing into the interior space.

An override device is described for use with a coupler of a circuit breaker. The override device comprising a cam member coupled to the coupler. The cam member comprising a slot. The override device also including an actuator coupled to the cam member and configured to move the cam member between an over-current protection position and an over-current relay override position and a push member coupled to the coupler. The slot configured to guide the push member to a first position when the actuator moves the cam member to the over-current protection position. The slot further configured to guide the push member to a second position when the actuator moves the cam member to the over-current relay override position to permit current flow through the circuit breaker.

A switching assembly having an interlock device for a selector switch is provided. The interlock device includes a flapper member rotatably coupled to a base member. The flapper member has an aperture disposed proximate to an aperture of a panel such that the selector switch extends through the apertures. The flapper member further includes an indented region and has a first operational position proximate to the panel and a second operational position disposed outwardly from the panel. When an arm portion of the selector switch is disposed within the indented region of the flapper member at the second rotational position and the flapper member is rotated to the second operational position, then the arm portion cannot be rotated outside of the indented region.
