Abstract
A hybrid circuit breaker consists of a series-connected vacuum interrupter and sulfur hexafluoride interrupter wherein the contacts of each are simultaneously operated. The sulfur hexafluoride interrupter is of the type in which an arc is rapidly rotated through a relatively static volume of sulfur hexafluoride. In one embodiment of the invention, the vacuum interrupter is replaced by a second sulfur hexafluoride interrupter in which the arc gap between the electrodes receiving the final arc to be interrupted is relatively smaller than the corresponding arc gap in the other sulfur hexafluoride interrupter.
