Abstract
A multipole circuit-breaker for each pole has an insulating feedthrough including a cylindrical first portion containing a vacuum bottle. The vacuum bottle comprises an insulating case closed by first and second endplates. The first metal endplate carries a first terminal outside the case and a fixed contact inside the case. The second endplate has a moving metal rod passing therethrough in sealed manner and carries a moving contact. The second endplate is electrically connected to the second cylindrical portion having a metal tube disposed coaxially therein. The metal tube is mechanically connected to the vacuum bottle and is electrically connected to the moving rod. The tube comprises a drive rod connected to the moving metal rod. The insulating feedthroughs of each of the pole are connected to a common metal bar disposed substantially at the junction between the first and the second portions of each feedthrough. The bar contains a control shaft common to the poles and connected to a drive mechanism. The drive rod of each pole is mechanically connected to the shaft. The tube comprises an endpiece fixed thereto and constituting a second terminal.
