An electrical arrangement for protection in a direct current high voltage electric system comprises an input connection with an input terminal, an output connection with a output terminal, a main disconnection component between the input terminal and the output terminal and at least one clamping circuit between the input terminal and the output terminal. The clamping circuit has a first connecting path and a second connecting path, arranged in parallel to each other. The first connection path comprises a storage coupling for temporarily buffering an overvoltage present between the input terminal and the output terminal. The first connection path also comprises an activatable switch for selectably connecting the storage coupling with the output terminal. The second connection path comprises a supply coupling for operating the activatable switch in dependency of the overvoltage.
