摘要： An electrical contactor includes a moveable core member having a first moveable core surface and a second movable core surface. The second moveable core surface is angled relative to the first moveable core surface. A stationary core member is mounted relative to the moveable core member. The stationary core member includes a pole arm having a first stationary core surface and a second stationary core surface. The second stationary core surface is angled relative to the first stationary core surface. In response to a magnetic field traversing a path defined by the stationary core member and the moveable core member, the first stationary core surface is magnetically biased to mate with the first moveable core surface and the second stationary core surface is magnetically biased to mate with the second moveable core surface to bring into contact an electrical contact member and an electrical contact element.

摘要： A circuit breaker having an arc quenching system is provided. The quenching system includes an ablative device positioned within a chamber. On end of the ablative device includes an opening that receives a stationary contact. A movable contact arm travels within a channel between the closed position and an open position. When an abnormal operating condition is detected, the circuit breaker trips causing the contact arm to move. This generates a plasma arc that evaporates material from the ablative device. The evaporated material generates a pressurized gas that cools and quenches the plasma arc to improve the performance of the circuit breaker during undesired operating conditions such as a short circuit.
摘要翻译：提供具有灭弧系统的断路器。淬火系统包括定位在室内的烧蚀装置。在烧蚀装置的末端包括接收固定接触件的开口。可动接触臂在关闭位置和打开位置之间的通道内行进。当检测到异常运行状态时，断路器跳闸导致接触臂移动。这产生等离子体电弧，其从烧蚀装置蒸发材料。蒸发的材料产生加压气体，其冷却和猝灭等离子弧，以在诸如短路的不期望的操作条件下改善断路器的性能。
