ABSTRACT:
A circuit breaker comprising an interrupting unit mounted in a vessel filled with a charge of arc extinguishing gas of uniform pressure and operating such that when the circuit is broken the arc extinguishing gas is compressed to increase its pressure, so that the high pressure gas will be blown against an electric arc established between the contacts to extinguish the same. The circuit breaker is formed therein with two paths for the high pressure gas blown against the arc, each path having an insulating nozzle mounted in it.
