Abstract
Electronic protection device for three-phase motors, essentially characterized in that it consists of an emitting element composed of three lamps, connected in parallel with each of the fuses of the protected motor; a receiver element, integrated by a circuit comprising a rectifying diode, three agglomerate type resistors, a photocell of cadmium sulfide, an electrolytic capacitor, a relay and two contacts actuated by the relay, one open and one closed; providing a fourth neon lamp that stays on for the duration of the fault and that constitutes a part of the rearm element, complemented by a pushbutton with two closed contacts and two open, all enclosed in a small box from which the pushbutton protrudes. Rearmament. (Machine-translation by Google Translate, not legally binding)
