A circuit (S) for protecting a DC network having DC loads (1) and connectable to the circuit (S), the circuit (S) is suitable and configured to supply the DC network with electric power via a three-phase rectifier (G) and wherein the circuit (S) includes a means (2, 3, 4, TH1, LS, CS, DU, DV, DW) for detecting an overvoltage, wherein the means is suitable and configured to detect an overvoltage at the input of the DC network, and the circuit (S) includes a means (2, 3, 4, TH1, LS, CS, DU, DV, DW) for transferring a current, wherein the means is suitable and configured to supply current to one or several current-carrying thyristors (THU1, THV1, THW1) of the rectifier (G), wherein the current causes the thyristor or thyristors (THU1, THV1, THW1) to turn off as soon as the detection means has detected an overvoltage. |
