Patent ID: 8859916

Claim:
An electrical cut-off device ( 1 ) with high making capacity provided with a control module ( 2 ) associated with at least one cut-off module ( 3 ) corresponding to a phase of an electrical network, the cut-off module comprising: at least one moving contact ( 5 ) associated with at least one pair of fixed contacts ( 4 ), the at least one moving contact ( 5 ) being coupled with an actuator mechanism ( 6 ) controlled by the control module ( 2 ) so as to be movable between at least one switched-off position, in which the at least one moving contact is spaced from the at least one pair of fixed contacts and the electrical circuit is open, and a switched on position in which the moving contact is resting on the at least one pair of fixed contacts and the electrical circuit is closed, wherein the electrical cut-off device ( 1 ) comprises at least one set ( 5 , 5 ′) of several moving contacts ( 5 A-C; 5 A-F) associated with the pair of fixed contacts ( 4 ), the at least one set of several moving contacts ( 5 , 5 ′) are parallel and offset in space with respect to each other in order to stagger in time approach of the moving contacts on the pair of fixed contacts when closing the electrical circuit, the at least one set of several moving contacts ( 5 , 5 ′) including at least one central moving contact ( 5 A) arranged ahead of the other moving contacts ( 5 B-C; 5 B-F) arranged laterally around the central moving contact ( 5 A) so that the at least one central moving contact ( 5 A) is the first to establish current when closing the electrical circuit and the last to interrupt current when opening the circuit.
