摘要
At least one of the contacts includes a central channel opening out towards the other contact in order to enable gas coming from the arc-control chamber during an opening stage to be discharged. According to the invention, the other contact carries an insulating member that ablates under the effect of an electric arc forming in the arc-control chamber in order to give rise to a large and fast increase of pressure within the chamber.
