摘要： An arc quenching device for a circuit breaker having a stationary contact member and a moving contact member includes a magnetic element formed of an arc quenching core and a base plate. The arc quenching core includes a back wall, and two side walls extending from lateral sides of the back wall. The base plate extends substantially perpendicularly from a lower side of the back wall in a direction as in the side walls, and is fixed to the stationary contact member. The base plate includes a U-shaped magnetic driving core situated near a stationary contact point and extending upwardly from the base plate to surround the stationary contact point, and an arc horn integrally formed with the base plate and obliquely extending toward the back wall from a portion near the stationary contact point. Arc formed between the stationary contact member and the moving contact member is moved by magnetic driving force formed by the magnetic driving core to the arc quenching core to be quenched therein through the arc horn.

摘要： A contactor device of a repulsion-type circuit breaker includes a first movable contactor with a first movable contact to be driven by an open-close mechanism; a fixed contactor; a second movable contactor having second and third movable contacts; a first contact spring for urging the first movable contactor toward the second movable contactor; and a second contact spring for urging the second movable contactor toward the first movable contactor and the fixed contactor. The first movable contactor, fixed contactor, and second movable contactor are arranged such that when an over-current flows, an electromagnetic repulsive force is generated so that the first and second movable contactors are rotated against the first and second contact springs to open between the first movable contact and the second movable contact and between the fixed contact and the third movable contact before the open-close mechanism opens the first movable contact.

摘要： A circuit breaker includes a movable contact, a fixed contact, a switching device, a switching operation handle, and an over-current tripping device. The switching device has a switching lever connected to the handle, a toggle linkage having an upper link and a lower link for connecting to the movable contact, a tripping mechanism for activating the toggle linkage in response to over-current, and an operation spring tightly stretched between the switching lever and the toggle linkage. A locking member is provided in the switching device for interconnecting the toggle linkage and the switching lever and for restricting a movement range of the switching lever according to an operational position of the toggle linkage. When main-circuit contact points are stuck, the locking member restricts the movement of the switching lever and prevents the handle from moving to the OFF position.
