Abstract
A gas tube arrester protector for protecting a pair of telephone lines from high voltage or surge current includes an insulating housing in which is disposed a three electrode gas tube overvoltage arrester having a pair of line electrodes and a ground electrode. The ground electrode is coupled to ground potential and each of the line electrodes is coupled to one of the telephone lines through a terminal line, a supporting terminal and a fusible link. The fusible links are in thermal relationship with the line electrodes and extend through cavities formed by spacers disposed adjacent each of the line electrodes. Whenever the line electrodes are heated sufficiently during an extended fault condition, the fusible links melt within the spacer cavities such that the line electrodes are disconnected from the terminal lines and thereby from the fault occurring on the telephone lines. The gas tube arrester, the spacer, the supporting terminal and a portion of the terminal lines are fixedly mounted in the housing by an insulating potting compound which fills a portion of the inside of the housing. The remaining portion of the housing can be filled with an inert insulating fill or powder.
