Understanding the 4 Pole MCCB

4 pole mccb

A 4 pole MCCB is a type of circuit breaker that offers four distinct poles or terminals for connecting wires. These poles typically include three live conductors (L1, L2, L3) for phase connections and one neutral conductor (N) for the ground or neutral line. The primary function of a 4 pole MCCB is to interrupt the flow of electric current when a fault occurs, such as a short circuit or overload, protecting the electrical system from damage.
