A circuit breaker system is disclosed in the present application. The circuit breaker system includes a housing to hold an electrical interrupter within an internal region separated from an external ambient region. The electrical interrupter includes at least a first pair of electrical contact elements that are movable between open and closed positions. A voltage limiter, such as a metal oxide varistor (MOV), is connected across the pair of electrical contact elements to receive and dissipate a transient voltage when the first pair of electrical contacts is moved from a closed position to an open position, thereby reducing undesired arcing and premature wear or erosion of certain electrical components. 在本申请中公开了一种断路器系统。该断路器系统包括壳体，以将电断续器保持在与外部环境区域分离的内部区域内。电断续器至少包括在断开与闭合位置之间可移动的第一对电触头元件。当第一对电触头从闭合位置移动到断开位置时，电压限制器(诸如金属氧化物变阻器(MOV))跨该对电触头元件连接以接收和耗散瞬态电压，从而减少不期望的电弧放电和某些电部件的过早磨损或腐蚀。
