摘要： In a circuit breaker utilizing a toggle link mechanism, the reset operation is facilitated. A block link (26) including a reset pin (27), a first hole (29) and a second hole (30) is provided. The reset pin (27) is inserted into a circular arc shape third hole (31) formed concentric with the rotation of a trip lever (18) formed at a secured frame (13). An actuating pin (28) of a handle lever (17) is inserted into the first hole (29). A shaft (21) provided at a movable contact holder (19) is inserted into the second hole (30). By this mechanism, the friction in the reset operation can be reduced to allow the reset operation to be perform by a smaller force. As a result, an auxiliary handle is not required. The handle and electrical operation devices can be reduced in size. Also, the operating handle (35) is prevented from moving to the OFF position when the switching contacts are welded.

摘要： A trip device of a circuit breaker that operates speedily when an enormous abnormal current such as short-circuit current flows is provided. The trip device includes a pressure detection space (40) having a wall portion formed of a repeatedly usable thin plate (40b), an operating rod (43) which protrudes from the pressure detection space when the pressure in the pressure detection space increases, and a return spring (44) which returns the operating rod. The pressure detection space is arranged in the vicinity of switching contacts, and the operating rod is arranged to release a trip latch mechanism (47) when it protrudes.

摘要： A multipolar circuit breaker of great breaking capacity prevents arc gas from blowing out from the side at the time of cutting off a short-circuit current. A stationary contact (3) and a movable contact (6) generating arcs when a short-circuit current is cut off, and an arc extinguisher (9) extinguishing the arc are stored in an arc extinguisher casing (1). By forming the ceiling (1b), the bottom (1a) and the sidewalls (1c) connecting the ceiling and the bottom of the arc extinguisher casing (1) in continuity so that no gap is formed by an outward internal pressure, blow out of arc gas from the sidewall portion is suppressed.

摘要： A trip device of a main circuit breaker is provided which causes only a branch circuit breaker to be set into a tripped state when an abnormal current occurs at a load of the branch circuit breaker while keeping a closed state of the main circuit breaker. The trip device of the circuit breaker has a structure including a trip latch mechanism (15) for opening switching contacts, a stationary core (18), a movable core (19) which is attracted to the stationary core (18) to release the latch mechanism (15) of a trip lever, an operating pin (22) for interrupting movement of the movable core (19) while the movable core (19) is attracted, an operating spring (23) charged with force when the movable core (19) is attracted, and an inertia roller (21) holding the operating pin (22), kicked when the operating spring (23) discharges the force, and moved to a position which does not interrupt movement of the movable core (19). Accordingly, this structure allows a selective tripping system to be implemented simply with small size and low cost.
