  • Overvoltage protection element system
    Patent number: 6529360
    Abstract: An overvoltage protection element for diverting transient overvoltage, with two electrodes (3, 4), each of which has a current terminal (1, 2), an air-breakdown spark gap (5) between the electrodes (3, 4) and a housing (6) which holds the electrodes (3, 4). The overvoltage protection element with an air-breakdown spark gap (5), 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 (3, 4) being located parallel to one another.
    Type: Grant
    Filed: August 28, 2001
    Date of Patent: March 4, 2003
    Assignee: Phoenix Contact GmbH & Co.
