Abstract
An overvoltage protection element for diverting transient overvoltages, with two electrodes ( ), each of which has a current terminal ( ), an air-breakdown spark gap ( ) between the electrodes ( ) and a housing ( ) which holds the electrodes ( ). The overvoltage protection element with an air-breakdown spark gap ( ), with reference to the operating voltage, the lightning surge current and network follow current carrying capacity behavior and the network follow current extinguishing behavior meets current requirements in a special way by the electrodes ( ) being located parallel to one another.
