A module for a high- and medium-voltage electric station, comprising: a supporting frame, which has a fixed part and a movable part; first actuation means, which are suitable to move said movable part; first and second sets of three insulating posts, arranged on the fixed part along two corresponding rows; first and second disconnection contacts being respectively associated with the insulating posts of the first and second sets and being electrically connectable, in input and in output with respect to the module, to corresponding electric terminals. The particularity of the modules consists of the fact that it comprises a set of three multifunctional interruption assemblies, each of which comprises: a supporting insulator, arranged on the movable part and connected in an elbow-shaped configuration to a containment insulator which contains at least one interruption unit which has a fixed contact and a movable contact which is operatively connected to second actuation means; third and fourth disconnection contacts, which are electrically connected to the interruption unit and are connected, in a disconnectable way, to the first and second disconnection contacts, respectively; the actuation of the movable part producing a movement of the multifunctional assemblies between a first position, in which the third and fourth disconnection contacts are respectively connected to the corresponding first and second disconnection contacts, and a second position, in which they are disconnected therefrom. Further, the first and/or second actuation means comprise a motor with position control.
