Abstract
The invention relates to an interrupting chamber for a high-voltage circuit breaker of preferably greater than at least 52 kV adapted to break all currents of value less than or equal to the short-circuit interrupting capacity of the circuit breaker, including asymmetric currents comprising an arc contact, an insulating arc blow-out nozzle having a through hole adapted to be blanked off by a valve, an insulating component which forms two channels, one of which is located between the insulating component and the arc contact, and wherein the hole is in communication with the channel.
