    • A miniature circuit breaker with two thermal-magnetic poles has an electronic trip device providing ground fault, and sputtering arc fault (if desired), protection located entirely in a large central compartment of a molded housing between compartments housing the two mechanical poles. The current rating of the circuit breaker is increased by a gas vent channel extending between the two mechanical pole compartments adjacent the respective breaker contacts which allows gases generated by arcing during current interruption to expand into both outer compartments, thereby permitting the circuit breaker to interrupt larger short circuit currents. The gas vent channel extends through, but does not communicate with, the central electronics compartment.
    • 具有两个热磁极的微型断路器具有提供接地故障的电子跳闸装置,以及溅射电弧故障(如果需要的话),保护部分完全位于容纳两个机械极的隔室之间的模制外壳的大型中央隔室中。 断路器的额定电流通过在相邻的断路器触点之间的两个机械极室之间延伸的气体通道而增加,这允许在电流中断期间通过电弧产生的气体扩展到两个外部隔室,从而允许断路器中断更大的 短路电流。 气体通道延伸穿过中央电子室,但不与中央电子室连通。

    • A circuit breaker includes a molded housing having a base and a cover forming a recess. A cylindrical steel pivot pin is disposed in the recess of the housing. Fixed and movable separable contacts are disposed within the molded housing. An operating mechanism is disposed within the molded housing for moving the separable contacts between an open position and a closed position. The operating mechanism includes a cradle having a latch portion and a generally U-shaped pivot portion which pivotally engages the cylindrical steel pivot pin. A trip mechanism cooperates with the operating mechanism to trip open the separable contacts. The trip mechanism includes a portion which engages the latch portion of the cradle when the separable contacts are in the closed position.
    • 断路器包括具有基座和形成凹部的盖的模制外壳。 圆柱形的钢制枢轴销设置在壳体的凹部中。 固定和可移动的可分离触点设置在模制外壳内。 操作机构设置在模制外壳内,用于在打开位置和关闭位置之间移动可分离触点。 操作机构包括具有闩锁部分和大体上U形枢转部分的托架,该枢转部分枢转地接合圆柱形钢枢轴销。 跳闸机构与操作机构配合以使可分离触点断开。 脱扣机构包括当可分离触点处于关闭位置时与托架的闩锁部分接合的部分。

    • A reverse fed single pole miniature ground fault circuit breaker includes a housing, a line termination on the lower portion of the housing, and a load termination on the upper portion of the housing. Separable contacts are disposed between the line termination and the load termination. A handle and operating mechanism form a manual mechanism for manually operating the separable contacts. The handle has an upper position in which the separable contacts are closed and a lower position in which the separable contacts are open. A ground fault circuit interruption trip circuit opens the separable contacts in response to predetermined ground fault current conditions and is powered through those separable contacts. In this manner, when a power source is electrically interconnected with the line termination on the lower portion of the housing, when the handle is in the upper position, and when there is none of the predetermined ground fault current conditions, the ground fault circuit interruption trip circuit receives power through the separable contacts.
