摘要:
A spring offset device is structured to extend between a circuit breaker frame assembly and a trip mechanism. The offset device includes an offset member disposed on a trip device banana link, a spring anchor disposed on the frame assembly, and a spring extending between the offset member and the spring anchor. The spring anchor is spaced from the hatchet pin assembly and, preferably positioned so that the longitudinal axis of the spring remains on a single side of a hatchet pin assembly axis as the banana link moves between a closed position, an open position, and a reset position. The offset member and the spring anchor are structured so that, when the hatchet plate is in the closed position, the spring creates an opening force on the hatchet plate biasing the hatchet plate toward the open position, and when the hatchet plate is in the reset position, the spring creates a closing force on the hatchet plate biasing the hatchet plate toward the closed position.
