ELECTRIC PROTECTION APPARATUS COMPRISING AT LEAST ONE SWITCHING MODULE CONTROLLED BY A CONTROL DEVICE WITH AN ELECTROMAGNETIC COIL

摘要

The electric protection apparatus has remote control device comprising an electromagnetic coil (18) designed to act on the contacts (13,15) to bring opening or closing of the contacts. The coils (12,21) of switching modules are substantially in the plane parallel to the plane of mounting support. A plate (22) made of ferromagnetic material is dimensioned to sensibly completely covers the coil of control device. The plate performs magnetic guiding of the arc as soon as separation of the contacts takes place so as to increase the propulsion component of the Laplacian force acting on the arc.
