Abstract
An electrical cut-off device provided with a control module associated with at least one cut-off module corresponding to a phase of an electrical network in which the cut-off module includes a set (5) of several moving contacts (5A-C) associated with one pair of fixed contacts. The moving contacts of the set (5) of several moving contacts (5A-C) are parallel and offset with respect to one another in order to stagger, in time, an the approach of the moving contacts with the pair of fixed contacts when closing the electrical circuit.
