Claims18
A circuit breaker including a housing having a front wall, a rear mounting wall, a pair of side walls and a pair of end walls extending between the front and rear walls to define an outer boundary, the housing having a guide means adjacent the rear wall, the rear wall having a stop edge and at least one fastening recess for mounting on a rail, a mounting clip mounted in the guide means, the mounting clip having a rail engaging portion extending into a fastening recess and a release head portion for disengaging the clip from the rail, the mounting clip being movable into and out of the fastening recess from an operating position with the rail engaging portion engaged with the rail to a disengaged position, wherein, in the operating position, the release head portion of the mounting clip is located within the outer boundary defined by the circuit breaker housing, the mounting clip further having a stop face removably engaging the stop edge and limiting the movement of the mounting clip.
A circuit breaker comprising:
- a housing having a front wall, a rear mounting wall, a pair of side walls and a pair of end walls extending between the front and rear walls to define an outer boundary, the housing having a guide means adjacent the rear wall, the rear wall having at least one fastening recess for mounting on a rail;
- a bracket having a screw retaining mounting head for mounting the bracket and a pair of spaced apart engagement legs demountably engaging the housing;
- and
- a mounting clip mounted in the guide means, the mounting clip having a rail engaging portion extending into a fastening recess and a release head portion for disengaging the clip from the rail, the mounting clip being movable into and out of the fastening recess from an operating position wherein the rail engaging portion is engaged with the rail and the release head portion of the mounting clip is located within the outer boundary defined by the housing to a disengaged position wherein the rail engaging portion is disengaged with the rail.
