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： A handle-operating mechanism for a circuit breaker includes a rotary operating handle for opening and closing a main-circuit contact of a circuit breaker, a rotating gear operably connected to the operating handle and having a first engaging device, and a contact opening-and-closing mechanism having a toggle gear meshing with the rotating gear. A clutch gear is connected to the operating handle to be interposed between the operating handle and the rotating gear, and has a second engaging device. An idle stroke is formed such that when the circuit breaker is turned on, the operating handle runs idly after rotation of the operating handle has been started and before the second engaging device engages the first engaging device to drive the rotating gear for actuating the toggle gear.

摘要： A circuit breaker includes an opening and closing mechanism section with an opening and closing lever, and an alarm-outputting plate operating in response to a tripping operation. A case for the circuit breaker has a plurality of switch housing sections formed on a top side thereof, in which are installed an auxiliary switch for detecting an ON/OFF state of a main circuit contact and/or an alarm switch for detecting a tripping operation. The opening and closing lever and the alarm-outputting plate have outputting projecting pieces, respectively, laterally spaced apart from each other corresponding to the respective housing sections, for transmitting mechanical output signals to the switches. When the auxiliary and alarm switches are installed, the auxiliary switch is linked to the outputting projecting piece of the opening and closing lever, while the alarm switch is linked to the outputting projecting piece of the alarm-outputting plate. The auxiliary switch and the alarm switch are installed in arbitrary combinations to the circuit breaker.

摘要： In a make-and-break mechanism for use in a circuit breaker, an alarm output plate 56, which is disposed so as to be slidable in the vertical direction along the frame (cover plate) 27 of the make-and-break mechanism, is secured to the engaging projection 27d of the cover plate 27 through a pair of right and left guide holes 57 formed therein. At the same time, one end of a handle spring 59, which, in the trip operation, is used to rotate an operation handle 26 to a trip display position, is caught on the alarm output plate 56. In case where a latch receiver 47 is driven or rotated by the overcurrent detect portion of the make-and-break mechanism and the secured condition of a latch is thereby removed, the electric circuit of the circuit breaker is broken due to the stored energy of a main spring 64 and, in this case, the alarm output plate 56 is driven or slided in the lateral direction and thus the secured condition of the alarm output plate 56 is removed, so that the alarm output plate 56 is driven in the upward direction due to the spring force of the handle spring 59 to thereby operate an alarm contact.

摘要： A U-shaped magnetic plate is positioned on the side of a movable contact shoe opposite to a fixed contact shoe, and the tips of the respective legs of the magnetic plate face via a gap the movable contact shoe in a closed condition of the movable contact shoe. A magnetic plate is attached to the surface of the movable contact shoe at the side of the fixed contact, so that the magnetic plates form a closed magnetic circuit surrounding the movable contact shoe. If a high current, such as short circuit current, flows, a magnetic flux passing through the closed magnetic circuit induces an attractive force between the upper end surfaces of the U-shaper magnetic plate and the end surface of the magnetic plate. Accordingly, the movable contact shoe is rapidly opened to quickly interrupt the current, before a signal from an overcurrent trip apparatus operates an opening and closing mechanism. The opening speed of the movable contact shoe is increased when high current flows.

摘要： A circuit breaker includes a current path for first and second contacts connected in series in an insulative container. When an overcurrent occurs by over load, the second contact is opened based on a command from a time delay trip portion of an overcurrent trip device. When a short-circuit current occurs, the first and second contacts are opened based on a command from an instantaneous trip portion of the overcurrent trip device. Since the first and second contacts are contained in a common container, the wiring works between the first contact and the second contact is unnecessary. Since the first and second contacts are opened in the instantaneous trip, interruption of a high short-circuit current is facilitated.

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： A switching mechanism for a circuit breaker includes a frame; a latch rotatably supported on the frame; a holder rotatably supported on the frame and having a movable contact; a handle lever rockably supported on the frame by lever shafts; a toggle link formed of first and second links rotationally connected by a toggle shaft; and a switching spring. A free end of the first link is rotatably connected to the latch, and a free end of the second link is rotatably connected to the holder. The first and second links generally overlap each other to reduce the movement range of the toggle link to miniaturize a switching mechanism. The switching spring is situated between the toggle shaft and the handle lever at a side opposite to a switching handle with respect to the lever shaft. When the handle lever is moved, operational force of the switching spring relative to the toggle link is reversed to rotate the holder with the movable contact, and when the latch is disengaged, the operational force of the switching spring relative to the toggle link is reversed to rapidly rotate the holder to thereby trip the movable contact.
