Patent ID: 8902027

Claim:
An electric protection apparatus comprising at least one switching module and a control device having an electromagnetic coil located adjacent, side-by-side, said switching module, said switching module comprising a switching coil, and two contacts one of which is movable with respect to the other between a first position in which the contacts are closed and enable current to flow and an open position in which the current is interrupted between the contacts, the electromagnetic coil of the control device for commanding opening or closing of the contacts, the coil of the control device being located substantially facing the contacts of the switching module, the coil of the control device having a first axis extending in a Z direction, substantially perpendicular to a fixing plane, the switching coil of the switching module having a second axis extending in a Y direction substantially parallel to the fixing plane, the first axis extending substantially perpendicular to the second axis, a planar magnetic shield located between the control device and the switching module, closer to said control device and facing the coil of the control device, and comprising at least one ferromagnetic part dimensioned so that it covers the coil of said control device, said part for magnetic guiding of an arc to increase the propulsion component of the Laplacian force acting on the arc as soon as separation of the contacts takes place.
