It plays a crucial role in protecting people, appliances, and electrical systems from the dangers of excessive current. Unlike traditional fuses that melt when the current exceeds a safe level, an MCB is designed to switch off instantly and can be reset with a simple toggle, making it both reliable and convenient.
