Abstract
Improvements introduced in the overcurrent relays for the protection of electrical circuits, intended to be connected in series in the circuit to be protected, characterized by being composed, in addition to the appropriate fixed and mobile contacts that determine the opening and closing of the circuit, of a coarse winding, of a thin winding and, eventually, of a resistance, both the thin winding and the resistance being connected in parallel with the fixed contacts, while the coarse winding is connected in series with them, in such a way that the magnetic field concatenated the coiled winding reaches sufficient force to open the contacts when a certain predetermined intensity is exceeded, the magnetic field having to be concatenated to the other winding which, as a consequence of the opening, is traversed by a certain current, sufficient force to keep said contacts open.
