Circuit breaker is a device that can connect manually or automatically disconnect the electrical current flow in the event of a short circuit or overload currents that exceed the capacity of the circuit elements.
Switchgear in general means is that the equipment and circuit breaker serves as a liaison between the two sides with a specific purpose. In electric power system switchgear meanings and functions are: - Connecting and disconnecting the power source to the load side - Connect and disconnect electrical power source to the other electrical equipment - Connecting main electricity network grid branch
A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to operate immediately after detection of a fault condition by the relay and, by interrupting continuity, to immediately discontinue electrical flow. Switchgear is the combination of electrical disconnect switches and circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear fault downstream. This type of equipment is directly linked to the reliability of the electric supply.
