    摘要： A compact, high capacity circuit breaker includes two breaking portions mounted in a single casing, with movable contacts for each portion disposed in series with one another and supported by a common switching shaft. Both portions of the breaker are tripped by either an overcurrent condition or manual operation, and the positioning of the common switching shaft maintains both breaking portions in the open state.

    摘要： A circuit breaker having stationary contactors provided for all of the poles thereof. Movable contactors are provided for all of the poles in correspondence to the stationary contactors. Stationary contacts are provided on the end portions of stationary contactors and movable contacts are disposed on the end portions of the movable contactors. The movable contactors are movable from the stationary contactors by electromagnetic force to open respective circuits before the circuit breaker is opened by an overcurrent tripping device when large current such as short-circuit current flows. Holders adapted to hold the movable contactors of all of the poles are mounted on a common rotatable insulating rod, one of the holders being provided with a latch which is turnable around a rod provided on the holder. A slot is normally engaged with the latch, and when disengaged from the latch, a rod can be turned by the holder. A spring operates to engage the latch with the rod until an electromagnetic moment acting on the latch generated in any of the poles or the sum of electromagnetic forces generated in all of the poles reaches a predetermined value. When a predetermined value is exceeded, the movable contactors of all of the poles are simultaneously moved from the stationary contactors to open the respective circuits with the aid of the insulating rod and the holders.

    摘要： A circuit interrupter includes two parallel pivoting contact arms, the lower of which is connected to a stationary conductor member using a clinch-type contact. The contact arm has an axle member rigidly attached thereto which is supported by a bearing member attached to the conductor. In one embodiment, the bearing member comprises a pair of bifurcated arms which are clamped about each end of the axle member. In an alternative embodiment, the conductor member lies generally parallel to the lower contact arm and is slotted to form a pair of elongated conductor arms, each of which supports a journal bearing member. One end of the axle is extended through each journal bearing.

    摘要： A resettable high-voltage fusing device including a vacuum interrupter and an arrangement of magnetically displaceable rod members which are displaced by the magnetic forces resulting from overload currents flowing through them. For currents below the "blow" rating, a spring arrangement keeps the rods in place by applying axially opposing forces at the ends thereof, and the vacuum interrupter is kept closed. After rod displacement caused by overload current the vacuum interrupter opens in response to one of the springs released by displacement of the rods.
