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.

Properties of Sulfr hexafluoride (Sulfur Hexafuoride) GasHandling Nonfaulted insulating gasHandling Faulted Sulfr hexafluorideDisposal of Wastea) Toxicitysf 6 is odorless, colorless, tasteless, and nontoxic in its pure state. It can, however, exclude oxygen and cause suffocation. If the normal oxygen content of air is reduced from 21 percent to less than 13 percent, suffocation can occur without warning. Therefore, circuit breaker tanks shob) Toxicity Of Arc ProductsToxic decomposition products are formed when sf6 gas gas is subjected to an electric arc. The decomposition products are metal fluorides and form a white or tan powder. Toxic gases are also formed which have the characteristic odor of rotten eggs. Do not breathe the vapors remaining ic) Physical PropertiesSulfr hexafluoride is one of the heaviest known gases with a density about five times the density of air under similar conditions. gaz sf6 shows little change in vapor pressure over a wide temperature range and is a soft gas in that it is more compressible dynamically than air.
