An electrical breaker, or circuit breaker, is a safety device designed to protect an electrical circuit from damage caused by overcurrent, which can result from an overload or a short circuit. When an excessive amount of current flows through the breaker, it automatically trips, interrupting the flow of electricity and preventing potential hazards like overheating wires and fires. Breakers are resettable, unlike fuses, making them a convenient and essential component of modern electrical systems.
