A circuit breaker is also known as the automatically operated electrical switch that functions when a fault detected by interrupting the current flow. There are various sizes of circuit breaker which are from small devices up to large switchgear that used to protect low current circuit until high voltage circuit .
Example: In a modern urban substation where space is limited, a hybrid circuit breaker might be used to protect the main incoming feeder. The hybrid design allows for compact installation while providing reliable fault protection and efficient arc quenching.
Their results showed that semiconductor breakers have fast breaking speed, while semiconductor switches may be connected in series and parallel with the high voltage circuit breakers.
