A semiconductor current cutoff device, including a circuit having a first branch including an energy absorbing member and a second branch including a semiconductor switch, the semiconductor switch being connected in parallel with the first branch, a current measuring means for measuring the intensity of the electrical current at a connection terminal of the device, and an electronic control unit for controlling the semiconductor switch, programmed to control the opening of the semiconductor switch when the current intensity measured by the current measurement means reaches a predetermined value, the device then switching from a conductive state to a cutoff state, the circuit including a third branch including a mechanical switch, and the electrical control unit being programmed so that the semiconductor switch is closed before the mechanical switch.
