Abstract
Automatic switch with auxiliary magnetic circuit for the anticipated opening of the contacts; characterized in that a tripping mechanism is operated for the opening of the contacts by means of an electrothermal and electromagnetic system, said mechanism acting on an axle provided with trestles, each ridge being provided with a respective mobile contact carrier articulated thereon and subjected to the action of a spring that provides the closed contact pressure, characterized in that an auxiliary magnetic circuit combined with firing systems and with recuperating springs which cause the anticipated opening of the contact by rotating around its surface is provided in correspondence of each mobile contact. Axis of articulation, when a short-circuit current creates a magnetic field that travels through said magnetic circuit, independently of the intervention of the magnetic trigger and the intervention of the switch trigger mechanism (Machine-translation by Google Translate, not legally binding)
