Emerson Edco RJA-RJD Series

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 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).
