Abstract: 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.
