ABSTRACT:
A modular housing for a circuit breaker has first and second opposed side panels which engage one another at respective upper and lower edges defined by transversely extending flanges. The mated flanges define the upper and lower edges of the housing. When assembled, the side panels define an enclosure with front and rear openings, with grooves on the inner edges of the openings which receive tongues of respective modular front and rear panels of the circuit breaker housing. The front panel has an opening through which an operating lever protrudes when the housing is assembled, and the operating lever pivots on formations on the inner surfaces of the side panels. The modular construction of the circuit breaker housing allows different front and rear panels to be fitted to a common shell. For example, a range of circuit breakers having different operating handles and different terminal configurations can be provided at a relatively low cost.
