Definition and Construction

3 pole circuit breaker

A 3 pole circuit breaker is a switching device designed to protect an electrical circuit from damage caused by overloads, short circuits, or other fault conditions. It consists of three poles, each pole representing a phase in a three-phase electrical system. The breaker is typically composed of a set of contacts, an operating mechanism, and a trip unit that monitors the circuit conditions and trips the breaker when a fault is detected.
