Abstract: The DC electrical network comprises an electrical load supplied with electricity by an electrical power source to which the electrical load is linked by a first electrical line and a second electrical line. An overcurrent protection system comprising an input pole and an output pole is mounted in series on the first electrical line. The overcurrent protection system comprises an electronic switch mounted in series between the input pole and the output pole, an electrical current sensor, and a controller configured to control the electronic switch. It also comprises an electronic device linked to the input pole and to the second electrical line. The controller is configured to command a conducting state of the electronic device when a current measurement from the electrical current sensor is above a predetermined current threshold, then to command an opening of the electronic switch.
