The invention relates to a method (100) for operating a device having an electrochemical energy store, an electronic high-voltage switch and a DC protection circuit which is connected in parallel to the electronic high-voltage switch, the invention relates to a method for controlling a DC protection circuit comprising a series circuit consisting of at least one thyristor overvoltage protection member and at least one varistor, comprising the following steps: closing (110) the electronic high-voltage switch, in which a current flows between the electrochemical energy store and an attached load, monitoring (120) the current by means of an electronic controller, in which the current is controlled by means of a voltage regulator, and the current is controlled by means of a voltage regulator. Detecting if the current exceeds a threshold value, opening (130) the electronic high-voltage switch in accordance with the detected threshold value exceeding such that the current flows through the DC protection circuit, and opening (130) the electronic high-voltage switch in accordance with the detected threshold value exceeding such that the current flows through the DC protection circuit. A cut-off voltage of the at least one thyristor overvoltage protection component and of the at least one varistor and a blocking current of the thyristor overvoltage protection component are exceeded (140) such that the at least one thyristor overvoltage protection component becomes low ohm, the pulse energy generated by the opening of the electronic high-voltage switch is converted (150) into heat by means of the varistor, which is lower than (160) the holding current of the at least one thyristor overvoltage protection means such that the at least one thyristor overvoltage protection means is blocked.
