An overvoltage protection device comprises at least one overvoltage protection unit having at least one contact lug as well as a mechanical disconnection apparatus that is activated in the event of a thermal overload. The mechanical disconnection apparatus comprises a connection element that can be moved from a closed position to a current-interrupting or voltage-disconnecting position by a slider that is preloaded by spring force.
