Abstract
A module for detecting an electrical fault includes a housing; a first conductor and a second conductor; a first measurement toroid, positioned around the first conductor and around the second conductor, for measuring a differential current flowing between the first and second conductors; a second measurement toroid, positioned around the first conductor, for detecting an electric arc signal flowing through this conductor; a relay; an electronic processing circuit configured to switch the relay according to the current measured by the measurement toroids. The measurement toroids are aligned with one another and the first toroid takes the shape of an elongated tube and allows the differential protection to operate with its own current.
