A Four Pole MCB (Miniature Circuit Breaker) is designed to protect three-phase electrical circuits with a neutral wire, providing comprehensive protection for all four conductors: three live phases and one neutral. It is ideal for industrial and commercial applications that require protection across all phases and the neutral line. The four-pole design ensures that in the event of an overload or short circuit, all four connections are disconnected simultaneously, enhancing safety and system reliability. This type of MCB is commonly used in distribution boards and sub-distribution boards, offering robust overcurrent protection and ensuring balanced and secure operation of three-phase electrical systems.
