Switchgear is a general term used to refer to a range of switches, circuit breakers, fuses, etc., which are used in an electric power system to control, regulate and switch the circuit on and off. By controlling the circuit, switchgear protects and isolates electrical equipment from the power supply, enabling testing, maintenance and fault clearing work to be undertaken.
