An electrically-insulative terminal cover is arranged on the line end of a light industrial-rated circuit breaker to allow a close-fit arrangement between a plurality of such circuit breakers within a common enclosure. The terminal cover is in the form of a top piece and a perpendicular side piece. The top piece comprises a pair of notches for receiving a pair of electrical conductors connecting with a corresponding pair of circuit breaker electrical terminals. The side piece includes a pair of elongated notches adapted for receiving sides of a pair of adjacent circuit breakers. A center side piece between the elongated notches can be press-fit within a combined slot defined by slots in sides of a pair of abutting side walls of adjacent circuit breakers. The top piece provides electric isolation to a top of the electrical terminals while the side piece provides electric isolation to a front of the electrical terminals.

Light industrial circuit breaker terminal cover

A molded case circuit breaker unit having an accessory compartment within the circuit breaker cover, contains a field-replaceable fuse within the compartment for protecting an electric motor without tripping upon motor current reversal. Upon the occurrence of a short circuit within the protected circuit, the fuse operates to isolate the protected equipment and is conveniently replaced without disassembling the circuit breaker components.
