Abstract

The invention relates to an overvoltage protection arrangement comprising a horn spark gap located in a housing, with a chamber for arc quenching, wherein a trigger electrode is located in the ignition region of the horn spark gap, wherein a disconnecting element is provided that interrupts a connection between a trigger circuit and the trigger electrode, and thus disconnects the trigger electrode, wherein the disconnecting element is tripped or controlled by an evaluation unit that is subject to and reacts to the loading of a power follow-on current.
