The invention relates to a medium voltage electric distribution cell to be placed between two portions of an electric circuit so as to provide at least the functions of enabling the current flow between the portions, interrupting the current between the portions, cutting off the current, and grounding, respectively. The cell is characterised in that it comprises a switch (or circuit breaker) (1) of the vacuum cut-off technology, which can also be used as a selector and, in series with said switch (circuit breaker) (1), as a selector (2) with at least two positions, i.e. a current flow position and a position for grounding one of the circuit portions, respectively.

La présente invention concerne une cellule de distribution électrique moyenne tension destinée à être interposée entre deux parties d'un circuit électrique de manière à assurer au moins les fonctions respectivement de passage du courant entre les parties, d'interruption du courant entre les parties, de sectionnement du courant, et de mise à la terre. Cette cellule est caractérisée en ce qu'elle comporte un interrupteur (ou disjoncteur) (1) à technologie de coupure dans le vide réalisant également la fonction sectionneur et, en série avec ledit interrupteur (disjoncteur) (1), un sélecteur (2) à au moins deux positions respectivement une position de passage du courant et une position de mise à la terre de l'une des parties du circuit.
