Dual Primary Protector

Model: SA-4713-0001


The Dual Primary Protector is environmentally sealed against the elements. This, in cooperation with the gel filled IDCs, protects against the risk of corrosion or failure caused by nicked wires during stripping. Two set of test points are provided to validate dial tone on the primary and secondary phone lines.

A feature unique to the Dual Primary Protector includes the addition of secondary surge protection on each line, guarding the equipment in the house against lightning strikes and power crosses. 

The GDT (Gas Discharge Tube) is widely accepted as the best in the industry; our dual primary protection module is equipped with the Comtest IDC Connectors and will fit in any standard Subscriber Network Interface enclosure that incorporates a threaded ground post.

Our Dual Primary Protection Module has a small footprint and the dual port design makes it easy and efficient for any DSL Bonded Services.
