Differentiating circuit breakers is one of the main tasks for any electrical engineer. Circuit breakers are safety elements in electrical installations and systems, which operate automatically when an overload fault occurs. They also act as protection devices against overloads and overheating which could easily spark off fires. This is done by means of an electromagnetic coil or a bimetallic strip that opens the circuit once the current exceeds the set value. In addition, these features help to reduce the chances of accidents while extending the life of electrical appliances. In industry, electrically-operated machines and circuit breakers help enhance efficiency and safety.
