    Abstract: An overvoltage protection device module includes an electrically conductive first electrode, an electrically conductive housing electrode, and a varistor member formed of a varistor material and electrically connected between the first electrode and the housing electrode. The housing electrode includes a housing end wall and a housing side wall collectively defining a housing cavity, and first and second housing members joined together at a joint. The first housing member forms a first portion of the housing side wall and the second housing member forms a second portion of the housing side wall. The varistor member is disposed in the housing cavity.

    Abstract: A surge protective device includes a first electrical terminal, a second electrical terminal, and an overvoltage protection circuit connected between the first electrical terminal and the second electrical terminal. The overvoltage protection circuit includes a spark gap assembly between the first electrical terminal and the second electrical terminal. The spark gap assembly includes a first spark gap (SG) electrode and a second SG electrode defining a spark gap therebetween, and a trigger circuit operative to ignite a main electric arc between the first and second SG electrodes across the spark gap. The trigger circuit includes a groove defined in the second SG electrode, and a trigger member disposed in the groove. The trigger member is operative to assist formation of a trigger arc.

    Abstract: A gas discharge tube includes a housing defining a chamber, first and second terminal electrodes mounted on the housing, a plurality of inner electrodes located in the chamber, and a gas contained in the chamber. The inner electrodes are serially disposed in the chamber in spaced apart relation to define a series of spark gaps from the first terminal electrode to the second terminal electrode. The chamber is hermetically sealed.
