    摘要： A molded case circuit breaker includes a clear viewing window through its top cover to enable the position of its internally disposed separable electrical contacts to be externally visually discerned. A manually engagable handle extending through an opening formed in the top cover of the molded case of the circuit breaker has an electrically insulating strip or barrier secured thereto and movable therewith for covering the clear viewing window when the separable contacts are in their CLOSED position to prevent smoke and other arc products resulting from circuit breaker interruptions from obstructing the clear viewing window. The viewing window may be inserted in the top cover during the molding process or may be subsequently disposed in the top cover in the form of an insert fixedly secured thereto.

    摘要翻译： 模制外壳断路器包括通过其顶盖的清晰的观察窗，使得其内部设置的可分离电触点的位置在外部视觉辨别。 延伸穿过形成在断路器的模制壳体的顶盖中的开口的手动接合手柄具有固定到其上的电绝缘条或屏障，并且当可分离触点处于其闭合位置时可移动以覆盖透明观察窗，以防止 烟雾和其他电弧产品由于断路器的中断而阻碍了清晰的观察窗口。 观察窗可以在模制过程中插入顶盖中，或者可以随后以固定地固定在其上的插入件的形式设置在顶盖中。

    摘要： An integrated electronic trip molded case circuit breaker includes a trip unit circuit arranged on a printed wire board contained within the breaker enclosure along with at least one circuit breaker auxiliary accessory. The condition of the integrated circuit breaker contacts is visually ascertained by a color-coded operating handle skirt subjacent indicating windows on the cover of the circuit breaker enclosure. To deter the egress of ionized gas during overload current conditions through the circuit breaker, the handle skirt seals the operating handle opening from the external environment. A groove formed within the external portion of the operating handle cooperates with an edge surface of the enclosure cover to allow the operating handle to rotate between its fully "OFF" and "ON" positions.

    摘要： A molded case circuit breaker includes an operating mechanism position indicator having a plurality of electrically insulating cards or strips disposed beneath an opening in the breaker cover about a manually engageable handle of the circuit breaker for movement in response to movements of the handle along the cover opening. A first one of the cards includes a pair of spaced apart, laterally aligned red markings for providing an externally visually discernible indication that the operating mechanism of the circuit breaker is in its CLOSED position. The first card also includes a pair of spaced apart, laterally aligned white markings for providing an externally visually discernible indication that the operating mechanism of the circuit breaker is in its TRIPPED position. The second card is positioned beneath the first card and is of a substantially greater length than the first card. Disposed on the second card are a pair of spaced apart, laterally aligned green markings for externally visually indicating that the operating mechanism is in its OPEN position. The first and second cards are movable relative to each other and a lost motion connection is provided between the second card and the handle. The colored markings on the cards are viewable through a pair of laterally-aligned slots provided in the cover of the circuit breaker. The two cards also function as a mechanical and electrical barrier closing the opening of the cover of the circuit breaker through which the handle extends.

    摘要： A molded elongated arcuate shield is snap-fitted to a circuit breaker operating handle to achieve a lost motion connection thereto. The operating handle projects through an elongated wall opening in the circuit breaker housing and is movable longitudinally thereof. The shield is disposed between an arcuate interior surface of housing and an arcuate surface of an apron formed integrally with the handle. While the apron above is too short to close the wall opening for all positions of the handle, the apron in cooperation with the shield fully closes the wall opening for all positions of the handle. Latch tabs formed integrally with the shield engage a blocking formation internally of the housing to hold the shield stationary while the handle moves from its On to Trip position. In the former position ON indicia carried by the apron is viewable through an aperture in the shield through which the handle extends, and when the handle is in its Trip position the latched shield blocks the ON indicia from view. Labyrinth-type gas seals are provided adjacent the longitudinal edges of the wall aperture by longitudinally extending ribs formed integrally with the shield and extending into cooperating slots inside the housing wall.

    摘要翻译： 模制的细长弓形屏蔽件卡扣配合到断路器操作手柄以实现与其的运动连接。 操作手柄通过断路器壳体中的细长壁开口突出并且可纵向移动。 护罩设置在壳体的弧形内表面和与手柄一体形成的挡板的弓形表面之间。 当上述围裙太短而不能关闭手柄的所有位置时的壁开口时，围裙与护罩协作完全关闭了手柄的所有位置的墙壁开口。 与屏蔽件一体形成的闩锁接合住壳体内部的阻挡结构，以在手柄从其开启到跳闸位置的同时保持屏蔽静止。 在围裙的前一位置ON标记可以通过手柄延伸的屏蔽中的孔眼可见，并且当手柄处于其跳闸位置时，锁定的屏蔽件阻挡ON标记。 迷宫式气体密封件通过与屏蔽件一体形成并且延伸到壳体壁内的配合槽中的纵向延伸肋邻近壁孔的纵向边缘设置。
