ABSTRACT:
A circuit breaker of a current-limiting type, which is able to open quickly by using a magnetic repulsive force generated when currents of opposite direction flow through a fixed contactor and a movable contactor which are arranged in parallel to each other. The movable contactor opens or rotates around a supporting shaft. Then, a guide pin, secured at the base portion of the movable contactor, slides into a guiding longish opening and passes over a turning point formed in the longish opening. As a result, the line of action of a compressed spring force changes its direction in order to push up the movable contactor to the full open position.
