The invention relates to a circuit arrangement for protecting at least one component part (3) of a two-wire circuit, which component part (3) is connected, in series with a load (1), to an AC/DC current source (16), wherein the two-wire circuit has a rectifier (2), a clock-pulse generator (9) and a switch (3), wherein the rectifier (2) forms a DC circuit (12), the switch (3) is connected into the DC circuit (12) and the clock-pulse generator (9) outputs a clock signal T to the switch (3) in order to clock the DC circuit (12). The invention is characterized in that the circuit arrangement has a diode (4), wherein the forward direction of the diode (4) is from the anode KN of the diode (4) to the cathode KA of the diode (4), in that the cathode KA of the diode (4) is connected to the DC circuit (12), in that a periodic or a constant voltage from a first voltage source (6a) is applied to the anode KN of the diode (4), and in that the voltage is at least periodically greater than a preset threshold value S.
