Abstract
A fail-safe arrestor for electrical circuits utilizes a gas-filled tube to conduct at an over-voltage and also provides a clip to solidly couple the circuit to a ground lead at the melting from continuous current flow of an insulator interposed between an electrode and the ground lead, which insulator is a mesh with a plurality of passages allowing arcing between the electrode and clip at or above a predetermined voltage, and thus the ground lead, for a vented gas-filled tube.
