Abstract:
A contact system for a short-circuiting device for a switchboard, the contact system including at least one fixed contact piece connected to a main voltage source. The contact system also includes at least one moving contact piece and an insulating screen penetrable using the at least one moving contact piece so as to make contact between the at least one moving contact piece and the at least one fixed contact piece. The screen is disposed between the at least one fixed contact piece and the at least one moving contact piece.
