Abstract
A line protector for protecting telephone lines and the like from over-voltage or over-voltage current conditions includes a primary arrester of the gas tube type and a secondary or back-up arrester of the air gap type. The gas tube is housed within a cup, and a flange on one of the electrodes of the gas tube cooperates with an end portion of the cup to define an annular configuration for the air gap. An insulator is adjacent to the electrode flange and serves as an abutment for the end portion of the cup to assist in maintaining the air gap. The insulator also maintains the gas tube within the cup.
