Abstract
An overcurrent tripping device includes a tripping conductor connected to the main circuit; a fixed core inside which the tripping conductor penetrates and which is excited by current flowing through the tripping conductor; a movable core which is arranged to be opposed to the fixed core with a magnetic gap therebetween, and which forms a magnetic circuit in cooperation with the fixed core, and moves by being attracted by the fixed core when overcurrent flows through the tripping conductor; and a shaft fixed to the movable core to guide the movement of the movable core, and linked to the tripping mechanism of the circuit breaker, wherein the fixed core has a narrow gap formed in such a direction as to cross the magnetic circuit, so that magnetic saturation is suppressed by the narrow gap.
