Abstract

Short-circuit current limiting device, comprising at least one pair of cooperating contacts, one of which is fixed and the other is pivotally mounted around a fixed axis, being capable of being pressed against said fixed contact by the action of a pressure spring, the two contacts being shaped so that there is an electrodynamic repulsive force between them, capable of opening the moving contact when the current reaches a certain threshold of intensity, as well as a tilting equipment, capable of pivoting around of a fixed axis, parallel to the pivoting axis of the moving contact, under the action of electromagnetic means, fed by the current that circulates in one of the two contacts, when this current reaches the determined threshold of intensity, characterized in that the spring of pressure is directly anchored, at one end, to the movable contact, and at its other end, to a point appropriately chosen gone from the tilting equipment, and because the electromagnetic means are fed by the current that circulates in the fixed contact.
