Abstract

A cable trip assembly includes an actuating assembly, a mounting assembly, and a cable assembly. The cable assembly includes a cable member disposed within a sheath. The cable member has a first end and a second end. The cable member first end is coupled to a lever, which is part of the actuating assembly, which is structured to move between a first position and a second position, similar to the prior art lever. The cable member second end is coupled to the circuit breaker trip bar. The sheath is mounted on a rigid frame, preferably a portion of the circuit breaker. Thus, with the sheath held stationary, the lever can move the cable within the sheath between a first and second position as the lever moves between its first position and second position. Because the cable member second end is coupled to the circuit breaker trip bar, the trip bar is also moved between the trip bar first and second positions as the lever moves between the lever first position and second position.
