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： 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.

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 a circuit breaker, bag-like insulating covers 15 are formed integrally with each holder support 14. The holder support 14 is combined with a movable contact holder 13 for holding a movable contact 4, so as to press and retain the movable contact 4 by a contact spring 5. A pair of leg portions of a magnetic drive yoke 6 are inserted into each of the insulating covers 15. Thus, the magnetic drive yokes 6 are covered with the insulating covers 15 so that there is no risk of an interphase short-circuit. In addition, the magnetic drive yokes 6 are unitized with a movable contact mechanism so that the work of assembling the circuit breaker becomes easy.

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： 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.
