Abstract
A contactor device of a circuit breaker has a movable contactor to be raised or opened upon the occurrence of a short circuit current. One end portion of the movable contactor is bifurcated to form parallel claw members that engage a rotatable trip latch. When the movable contactor is raised due to a magnetic repelling force generated in the movable contactor and a fixed contactor during a short-circuit condition, the claw portions of the movable contactor are deformed due to a magnetic attractive force and are disengaged from the trip latch. The rotation of the movable contactor is restricted and it returns to the original positional relationship in which the claw members are engaged with the trip latch.
