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： 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 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 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： In relation to a circuit breaker, a left-side accessory switch storage section and a right-side accessory switch storage section are provided in a breaker case 1. A contact point of an ancillary switch 7 provided in one of the accessory switch storage sections is opened or closed in conjunction with an output protrusion 6a formed on an open-close lever 6 of an open-close mechanism section 3 on the main unit. A contact point of an alarm switch 9 provided in the remaining accessory switch storage section is opened or closed in conjunction with an alarm output plate 8 which operates in association with tripping action of the breaker. The output protrusion 6a is caused to oppose an operation lever 7a of an ancillary switch which is formed into a symmetrical bifurcated shape and which is provided in the accessory switch storage section. The alarm output plate constitutes a pivotal lever coupled to a toggle shaft 3a of the open-close mechanism section. An output protrusion 8a provided at the extremity of the pivotal lever is caused to oppose an operation lever 9a of the alarm switch provided in the accessory switch storage section.

摘要： A circuit breaker includes main circuit contact shoes disposed in a circuit breaker case and urged by a contact spring, a contact opening and closing mechanism located above the contact shoes and including an opening and closing lever, a toggle link, an opening and closing handle and a latch, and an overcurrent tripping device located above the contact shoes. The toggle link includes a first link extending between the opening and closing lever and a toggle shaft located above, and a second link extending between the toggle shaft and the latch to overlap the first link in the V-form, and an opening and closing spring extends between the toggle shaft and a tip of a handle lever coupled to the opening and closing handle to extend downward. As a result, a space occupied by the contact opening and closing mechanism section in the height direction can be reduced to make the circuit breaker more compact.

摘要： An insulated container of a circuit breaker is divided into three vertically-arranged portions including a case, a middle case, and a cover. A fixed contact shoe and a movable contact shoe are accommodated in the case. An opening and closing mechanism and an overcurrent trip device are accommodated in the middle case. A holder slidably passing through a hole in a bottom wall of the middle case by an operation of the opening and closing mechanism is moved linearly and perpendicularly to the bottom wall to open and close the movable contact shoe. A gap in the hole between the holder and the bottom wall is very small due to the straight movement of the holder, so that an arc gas generated in the case is completely shut down by the bottom wall and does not reach the opening and closing mechanism in the middle case during current interruption.
