Pole MCB, No. of Poles : Four

A pole Miniature Circuit Breaker (MCB) is a protective device used in electrical systems to automatically disconnect a circuit when an overload or short circuit occurs. Available in single-pole, double-pole, triple-pole, and four-pole configurations, it ensures the safety of electrical installations by preventing excessive current from damaging wiring or causing fires. The MCB operates by detecting abnormal current levels and quickly tripping to interrupt the circuit, thus protecting both the electrical devices and the system as a whole. Its compact design allows for easy installation in distribution boards, and it features a resettable switch to restore normal operation once the fault is cleared. Pole MCBs are widely used in residential, commercial, and industrial settings to provide reliable overcurrent protection and enhance electrical safety.
