Abstract
A device for protecting against a short-circuit occurring on a high-voltage DC power supply line between a DC source and an active load, the device including a bypass circuit formed of a contactor K3 and a fuse F2 connected in series and set up parallel to the active load via a line independent of the high-voltage DC power supply line, the bypass circuit being configured such that most of the current passes through it once the fuse F2 has melted.

A device for protecting against a short-circuit occurring on a high-voltage DC power supply line between a DC source and an active load, characterized in that it consists of a bypass circuit formed of a contactor K3 and a fuse F2 connected in series and set up parallel to the active load via a line independent of the high-voltage DC power supply line, the bypass circuit being configured such that most of the current passes through it until the melting of the fuse F2.
