WebThe design and working of a circuit breaker depend on its application and voltage rating. Moulded case technology (with air at atmospheric pressure) is used at low voltages (< 1000 V), whereas air-blast and vacuum circuit breakers are prevalent at medium voltages (< 72 kV). SF6 circuit breakers are normally used for high voltage systems (> 72 kV).
