Abstract
An electrical protection device capable of operating without auxiliary electrical power supply includes a control module configured to detect an electrical fault and a switching module, a first circuit including at least two normally-on JFET transistors and a switching member including a first contact. The switching module is configured so that, upon a switchover of the first contact when the current circuits, an electric arc is formed and so that the appearance of the electric arc generates an electrical signal transmitted to at least one of the transistors, the electrical signal driving the switching of the transistor.
