ABSTRACT:
A multi-terminal arrestor holder and connector module provides electrical connection between telephone lines and telephone repeaters by means of a single body module which houses one three-electrode gas tube lightning protector for each pair of telephone lines. Lightning protection is accomplished by ionization occurring between either of two electrodes and a grounded intermediate electrode. Replacement of the arrestors and repeaters is conveniently provided by the spring clip mounting arrangement integrally formed within the arrestor module so that damaged arrestors can be readily removed without interrupting telephone service.
