Abstract

An arc chute for a circuit-breaker has a chute member with arc splitters and an end member that seals off the chute member to the top. The end member has three barriers for arc gases, the first and the second barrier have webs with a more or less square cross-sectional shape which are arranged in double the pitch of the arc splitters. Situated above the second barrier is a cooling chamber, which is sealed off to the outside by the third barrier that is provided with outlet orifices.
