Abstract
A circuit interrupter including separable main contacts, an operating mechanism interconnected with the contacts, and a housing in which the contacts and the operating mechanism are disposed. A trip mechanism is disposed in the housing and includes a trip bar assembly that, when selectively rotated in a first direction, generates a tripping operation causing the contacts to open. The trip bar assembly includes a groove in which sits a torsion spring for rotationally biasing the assembly in a second direction that is opposite the first direction.
