Edco RJA-RJD Series

RJ-45 Telephone/Data

The Edco RJA and Edco RJD Series are four pair telephone/data line

protectors that implement advanced two stage hybrid design. These units

address over voltage transients with silicon breakover devices, while sneak

and fault currents are mitigated with PTC technology, which consists of solid

state resettable fuses.

The Edco RJA and Edco RJD Series incorporate Edco RJ-45 female jacks in and

out. The Edco RJA voltage clamp is set for C.O. Trunks and Analog Telephone

Extensions (with ring in voltage), and the Edco RJD voltage clamp is set for

Digital Extensions (no ring in voltage).
