Edco RJD-45 RJ45 4 pair digital Surge Protector.
RJD-45 surge protector.
The Emerson Edco RJA and RJD Series are multiple-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 RJA and RJD Series incorporate RJ45 female jacks in and out. The RJA voltage clamp is set for C.O. Trunks and Analog Telephone Extensions (with ring in voltage), and the RJD voltage clamp is set for Digital Extensions (no ring in voltage). Two-pair and four-pair models are available.
