摘要： A circuit breaker for high-speed current-limiting breaking of a three-phase current in the event of a short-circuit condition. The breaker has three pairs of fixed and movable contactors, the latter being arranged for pivoting movement on a common shaft. The center movable contactor is biased against an opposing holder, such that in the event of a short-circuit, the bias is overcome and the movable contactors separate in unison from the fixed contactors.

摘要： A breaking mechanism includes a latch receiver engaging a latch to allow a movable contact shoe to be closed, and a tripping device for rotationally driving the latch receiver to disengage the latch to open the movable contact shoe. An engaging surface of the latch engaging the latch receiver is formed as a projecting circular surface, whereas an engaging surface of the latch receiver engaging the projecting circular surface is formed as a recessed circular surface having a radius of curvature greater than that of the projecting circular surface. The center of the curvature of the recessed circular surface coincides with the axis of a support shaft supporting the latch receiver. The loads causing a tripping device to drive the latch receiver do not change even if the location of an engaging point is changed.

摘要： In a circuit breaker, a rotary-operating handle is linked with an opening and closing mechanism via a driving gear so that main circuit contacts can be opened and closed by rotating an opening and closing lever. A vertically moving handle lock lever is arranged between a tip of the opening and closing lever and the driving gear directly coupled to the operating handle, so that when the main circuit contacts are opened after being welded, the lock lever abuts against the driving gear to restrain the operating handle to the vicinity of the ON position, thereby restricting the movement to a contact-open indicating position. Further, an upward-inclined surface is formed in a stopper section located at a tip of the lock lever, so that if the contact welding is not severe, the lock lever can be pushed down to forcibly open the contacts.

摘要： In an overcurrent-tripping device for a circuit breaker, an electromagnet is used to open a movable contact shoe when a heavy current flows through a conduction path. A push rod is provided so as to contact the movable contact shoe. The electromagnet of the overcurrent-tripping device is located above the push rod so as to attract a movable iron core of the overcurrent-tripping device linearly along a moving direction of the push rod. When the heavy current such as a short-circuit current flows through the conduction path, the movable iron core is attracted to push the movable contact shoe via the push rod for rapid opening of the movable contact shoe. Thus, before a tripping operation of the opening-and-closing mechanism, the movable contact shoe is moved, so that the time required by the movable contact shoe for the opening operation is reduced.

摘要： In a movable contactor device in a circuit breaker, two contactor elements are arranged in such a manner that they are in parallel with each other and are independent of each other, to form a movable contactor for each phase. The two contactor elements have respective movable contacts separated from each other, and are rotatably coupled through a supporting shaft to a connecting conductor having three prong-shaped contact pieces. The number of contact points with the stationary contact can be increased as much.

The unit is fabricated inside a cover 1b of a circuit breaker body. Here, the cam and the ratchet are formed as common parts, and the driving spring is selected in accordance with the kind of circuit breaker.
