Abstract
Gas filled surge arrester is equipped with a thermally responsive short circuit switch for overload protection and air gap shorting for back up overload protection. The switch and air gap device is disclosed in three orientations; namely, separate and external to the gas tube; unitized with the air gap interior to the switch; and unitized with the air gap exterior to the switch. The unitized arrangements have application in circuitry with gas tubes where back up air gap protection of the thermal switch is desired.
