    Abstract: A device includes a current difference measurement module for measuring the difference between a current flowing in a positive contact of the electrical installation and a current flowing in a negative contact of the electrical installation, a low-pass filter for filtering the differential current, a full-wave rectifier without threshold module for rectifying the filtered current and a trip module for emitting a trip command when the rectified current is greater than or equal to a predetermined threshold for a predetermined duration. The device thus makes it possible to protect a DC-voltage electrical installation in a noisy environment.
