OriginsOperationArc InterruptionShort CircuitStandard Current RatingsTypes"Smart" Circuit BreakersOther BreakersSee AlsoAn early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses. Its purpose was to protect lighting circuit wiring from accidental short circuits and overloads. A modern miniature circuit breaker similar to the ones now in use was patented by Brown, Boveri Cie in 1924.
