Abstract

A vacuum interrupter has a cover base formed with an insertion opening for an axially movable moving contact rod carrying a moving contact. The moving contact rod is routed out of the vacuum interrupter in a vacuum-tight manner by way of a bellows. The bellows has a centering appendage which is formed by a tubular end piece of the bellows that runs parallel to the longitudinal axis of the bellows and is inserted into the insertion opening. The bellows moreover has a bellows base which is disposed on the centering appendage, runs substantially transversely to the longitudinal axis of the bellows, and is formed with a through-opening for the moving contact rod.
