摘要： An electrical enclosure for circuit breakers includes a busbar with a plurality of apertures equidistantly positioned along a length of the busbar so that insulating inserts and corresponding busbar connectors can be attached to the busbar to receive variously sized circuit breakers having different widths equal to an integer multiple of the center-to-center distance between the equidistantly positioned apertures.

摘要： An arrangement in an electrical switching device for protection against electrical arcs comprises a tripping mechanism, a stationary contact carrier, a movable contact carrier, an exhaust vent, an arc runner, and an arc extinguishing barrier. The stationary contact carrier has a stationary contact mounted thereon, and the movable contact carrier has a movable contact mounted thereon. In response to an overcurrent condition, the tripping mechanism causes the movable contact carrier to rotate from a closed position to an open position, thereby generating an electrical arc. In the closed position the movable contact abuts the stationary contact, and in the open position the movable contact is separated from the stationary contact. The arc extinguishing barrier is composed of an outgassing material and is located between the stationary contact and a portion of the tripping mechanism. The stationary contact is located generally between the portion of the tripping mechanism and the arc runner such that the arc runner draws the electrical arc away from the portion of the tripping mechanism. The exhaust vent is located generally in line with the initial direction of movement of the movable contact when the movable contact carrier begins rotating from the closed position to the open position.

摘要翻译： 用于防止电弧的电气开关装置中的布置包括跳闸机构，固定触点载体，可动触点载体，排气口，电弧流道和灭弧屏障。 固定触点支架具有安装在其上的固定触点，并且可动触头支架具有安装在其上的可动触头。 响应于过电流状态，跳闸机构使可动触头托架从关闭位置旋转到打开位置，由此产生电弧。 在关闭位置，活动触点与固定触点相接触，而在打开位置，可动触点与固定触点分开。 灭弧屏障由脱气材料构成，位于固定触点与脱扣机构的一部分之间。 固定触头通常位于跳闸机构的部分和电弧流道之间，使得电弧流道将电弧从脱扣机构的部分拉出。 当可动触头载体开始从关闭位置旋转到打开位置时，排气口大体上与可动触头的初始移动方向一致。
