What is MCB?

An MCB (Miniature Circuit Breaker) is an automatic electrical switch designed to protect a circuit from damage caused by overloads or short circuits. When it detects excessive current flow, it quickly trips and disconnects the electrical supply, preventing overheating, fire hazards, and equipment damage. MCBs are more reliable and safer than traditional fuses because they can be reset easily after a fault is cleared.

MCBs are widely installed in electrical panels in every space, such as residential, commercial, and industrial. These electrical safety devices can be installed separately for each lower circuit to protect the expensive connections and connected appliances. With quick response and simple circuit installations, these devices are very reliable and cost-saving compared to fuses.
