What is a 4 Pole Circuit Breaker?

4 pole circuit breaker

A 4 pole circuit breaker is a type of circuit breaker that provides protection for four separate circuits simultaneously. Unlike single-pole or double-pole circuit breakers, which manage one or two circuits respectively, the 4 pole version is designed to manage three-phase power systems and neutral lines. It is widely used in three-phase electrical systems where it is essential to disconnect all phases and the neutral line simultaneously in the event of a fault or overload.
