Abstract

A disconnector for interrupting an electrical circuit comprises a main conductor and a secondary conductor, a conductive blade rotating between a closed-circuit position and an open-circuit position, an insulating casing containing a vacuum ampoule with a fixed electrode and a movable electrode, and a lever system comprising a driven lever and a driving lever for actuating the movable electrode. An auxiliary electrode is provided on the driving lever. The disconnector operates such that, during circuit opening, the conductive blade interacts with the auxiliary electrode, activating the lever system. This movement opens the contact inside the vacuum ampoule, interrupting the current flow.
