A panel device includes a protective cover that has an insertion hole for an ON/OFF knob of a molded case circuit breaker and is formed to cover an exposed live part of the molded case circuit breaker and provided with an engaging part at a predetermined portion thereof; a cover support member that openably and closably supports this protective cover; and a cover locking member that engages with the engaging part when the protective cover is closed and restricts turning of the protective cover; wherein any one of the protective cover, the cover support member and the cover locking member is movably provided in conjunction with movement of the ON/OFF knob, and the engaging part and the cover locking member are engaged with each other or released from each other by the movement of the any one of those.

A circuit breaker, and method of assembling the circuit breaker, includes a circuit breaker housing defining an interior portion, and which includes a molded base and a separable cover. The molded base includes an interior surface and an exterior surface. The exterior surface of the molded base is operatively disposed outside of the interior portion of the circuit breaker housing, and the exterior surface of the base defines at least one current sensing unit receiving cavity configured to receive a current sensing unit therein. The molded base and separable cover are cooperatively disposed to surround the interior portion of the circuit breaker housing.

An electrical device includes a fixed support with supply lines and a distribution circuit to supply power to a contactor block. Each contactor block includes secondary lines, each connected to a supply line, and is movable between joined and disjoined positions. Each contactor block includes a switching device for switching all secondary lines of the contactor block between open and closed. The electrical device also includes a control block, movable between joined and disjoined positions. When in the joined position, each contactor block also is held in the joined position, an electronic monitoring device of the control block also being connected to the switching device of each contactor block to control switching of each switching device independently. When the control block is in the disjoined position, the switching device of each contactor block opens the secondary lines, while each contactor block is movable between its joined and disjoined positions.

A circuit protection apparatus includes separable contacts, an operating mechanism, an electronic trip unit storing a plurality of trip parameter combinations, wherein each of the trip parameter combinations specifies a certain value for each of a plurality of individual trip parameters, and a multi-position selector moveable among a plurality of predetermined positions and configured to enable selection of one of the predetermined positions. Each of the positions corresponds to a respective one of the trip parameter combinations, wherein the electronic trip unit is structured to, responsive to a chosen one of the plurality of predetermined positions being selected by the multi-position selector, cause the one of the trip parameter combinations corresponding to the chosen one of the plurality of predetermined positions to be used by the electronic trip unit to determine whether to cause the operating mechanism to trip open the separable contacts.
