 # GearSS64 & SS65 Series
Data/Signal Pipe Nipple

The EDCO SS64 and SS65 Series suppressors are designed for the water and waste-water industry. These multistage hybrid suppressors address overvoltage 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).
