Circuit breakers are electrical switches designed to protect an electric circuit from damage due to an overload or a short circuit. The main function of all circuit breakers is to detect a fault, whether in the device itself (common in small and low voltage breakers) or otherwise. Once a fault is detected the breaker must disrupt the charge by separating the contacts.
