An electrical MCB (Miniature Circuit Breaker) is a device designed to protect an electrical circuit from damage caused by excess current flow. It is a type of switch that automatically shuts off the electrical circuit when the current flowing through it exceeds a certain level.MCBs are commonly used in residential and commercial electrical systems as a safety measure to prevent damage to electrical equipment and potential hazards such as electrical fires. They are typically installed in the distribution board or fuse box and are designed to trip (shut off) the circuit when the current exceeds the rated capacity of the MCB.MCBs come in various sizes and ratings to accommodate different electrical loads. They are also available in different types, such as single-pole, double-pole, and three-pole configurations, to suit different applications.Overall, MCBs are an essential component of modern electrical systems, providing reliable and effective protection against electrical overloads and short circuits.
