Types of Circuit Breakers - EandM
www.eandm.comVoltage Rating Circuit breakers are also rated according to the maximum voltage they can handle. The voltage rating of the circuit breaker must be at least equal to the circuit voltage. The voltage rating of a circuit breaker can be higher than the circuit voltage, but never lower. For example, a 480 VAC circuit breaker could be
