• How to Find the Proper Size of Circuit Breaker? CB Calculator

    Use the correct size breaker. A single phase circuit breaker can’t be used for three phase supply voltage levels. A 3-Poles circuit breaker can be used on 3-Phase system using either 2 or 3 poles. A 3-Poles circuit breaker can be used on 1-Phase system only and only if indicated by the markings or instructed by user manual.
