EDCO Telecom/Datacom Surge Protection Products

Water and Wastewater Signal Surge Suppressors


SS64 & SS65 Series


EDCO SS64 and SS65 Series surge suppressors are designed for the water and waste water industry. These multi-stage hybrid surge suppressors address over voltage transients with gas tube and silicon avalanche technology. In addition, sneak and fault currents are mitigated with new "PTC" devices which consist of solid state resettable fuses. The units are encapsulated in stainless steel pipe nipples making them suitable for use in severe environments. The SS64 models protect a signal pair and the SS65 models protect a signal pair plus the cable shield (drain wire).
