Switchgear is the grouping of electrically disconnected switches, fuses or circuit breakers that are utilized to regulate, defend and segregate electrical equipment. Switchgears encompass fuses, isolators, and circuit breakers. Fuses are positioned after every disconnection as it acts as a sacrificial device to provide overcurrent protection of high voltage and the low voltage side of large power transformers. 

The global switchgear market is classified on the basis of component as Circuit Breaker, Fuses, bus bars, relays and others. The circuit breakers basically refer to the medium in which the breaker opens and closes. A relay is an electrically operated switch. Relays are used where it is necessary to control a circuit by a low-power signal or where several circuits must be controlled by one signal.
