Abstract
A circuit breaker includes a line terminal adapted to receive a line voltage having a nominal voltage value and an excessive voltage value, a load terminal, one or more neutral terminals, and separable contacts electrically connected between the line and load terminals. An operating mechanism opens and closes the separable contacts. A trip circuit cooperates with the operating mechanism to trip open the separable contacts. The trip circuit includes a solenoid having a trip coil with a threshold voltage for energization, a circuit adapted to detect an arc fault or ground fault trip condition and to responsively energize the trip coil with the line voltage, and a MOV adapted to detect an excessive voltage condition associated with the load and neutral terminals and to responsively energize the trip coil with at least the threshold voltage.
