摘要： Disclosed is an air circuit breaker including a switching mechanism formed of a plurality of links so as to compress a closing spring by converting a rotating operation of the rotational shaft and to generate a driving force derived from an elastic restoring force of the closing spring; and a switching shaft mechanically connected to the switching mechanism so as to transfer the driving force generated from the switching mechanism to a movable contact, wherein the switching shaft is provided with a pair of holders installed at both sides from a center of the switching shaft so as to rotatably support the switching shaft at a frame supporting the both sides of the switching mechanism. Accordingly, the operation deviation of the circuit can be minimized by preventing the switching shaft from being deformed when the circuit performs a switching operation, and the lifespan of the air circuit breaker can be increased by reducing abrasion of components.

摘要： A switching mechanism of an air circuit breaker that allows the overall size of the air circuit breaker to be minimal by making the width of the switching mechanism relatively small. The switching mechanism of the air circuit breaker includes both side plates, a main shaft, a main shaft lever, a first link, a closing spring unit, a charging cam, a rotational shaft of the charging cam, a third link, a driving lever, a spring support pin and an end portion supported by the spring support pin, and a third link elastic bias spring having an end portion supported by the spring support pin and an operation portion for providing elastic force onto one surface of the third link to bias the third link to be rotated in one direction. A third link elastic bias spring directly provides the elastic force onto the third link in order to minimize the distance between a pair of driving levers and thus minimize the width of the switching mechanism.
