Abstract
Abstract A Temperature Sensitive Electrical Regulating Device comprising a multi-electrode gas tube arrestor having electrically coupled to each electrode an electrically conductive coupling element comprising an electrically insulative outer covering defining a cavity, and an electrically conductive member contained within said cavity such that upon the reaching of a particular temperature, the electrically conductive member changes its physical state causing a break in the electrical conductivity of said conductive member thereby lifting the three electrode gas tube arrestor off the line.
