A Single Pole MCB (Miniature Circuit Breaker) is a compact, automatic switch designed to protect a single electrical circuit from overloads and short circuits. Typically used in residential and light commercial applications, it controls the flow of electricity through one phase and provides reliable overcurrent protection. When the current exceeds the rated capacity, the MCB automatically trips, disconnecting the circuit to prevent damage or fire hazards. Single pole MCBs are commonly installed in distribution boards, consumer units, and panel boards, offering a quick and easy reset mechanism to restore power once the issue is resolved.
