Abstract
A circuit-breaker includes first and second permanent contacts, a support tube for a mobile arc contact and a blast nozzle. At least one of these components is fixed via an interference fit. The blast nozzle abuts against one end of a tubular support member with an annular end flange. It bears at the opposite end against a first permanent contact end-piece which is fixed by a clamping ring to the annular flange of the support member.
