MCB stands for Miniature Circuit Breaker. MCB is an electrical switch that automatically protects an electrical circuit from damage caused by overload or short circuit. It is a type of circuit breaker that is commonly used in residential and commercial buildings. MCBs are designed to trip and disconnect the circuit when excessive current flows through it, preventing damage to the electrical equipment and wiring. They are compact in size and provide better protection compared to traditional fuses. MCBs have different ratings, such as 6A, 10A, 16A, etc., which determine the maximum current they can handle. They can be easily reset after tripping, unlike fuses that need to be replaced. MCBs have a mechanical mechanism that trips the switch when the current exceeds the rated value. They are an essential component of electrical distribution systems to ensure safety and prevent electrical hazards.
