Abstract
A power shut-off module includes an insulating housing, two pairs of fixed contacts and two movable contacts rigidly attached to an item of movable equipment that is movable in translation in the housing between an open position and a closed position. The module includes an insulating shield device having a fixed end rigidly attached to the housing and a movable end rigidly attached to the item of movable equipment, and which has a length that is variable between an extended position when the item of movable equipment is in the open position and a retracted position when the item of movable equipment is in the closed position, in order to create a dielectric barrier between the fixed contacts of one and the same pair of fixed contacts.
