Self-contained mechanism on a frame

Abstract

A unitary operating mechanism assembly for a circuit breaker that includes a frame assembly having a planar member with a first pivot point located thereon, a handle member rotatably attached to the frame assembly at the first pivot point and structured to move between a first, closed position, a second, open position having an intermediate position therebetween, and a third, reset position, an operating arm coupled to the handle member and structured to move between a first and second position, and a trip device attached to the frame assembly and structured to move the handle member between the first, closed position and the intermediate position upon the occurrence of a predefined condition. The trip device causes the handle member to rotate upon the occurrence of a predefined condition, such as an overcurrent, thereby causing the operating arm to rotate and wherein none of the components except the frame assembly is attached to the housing. That is, the handle member, operating arm, or trip device are not attached to a circuit breaker housing.
