TM
The Edco SS64 and Edco SS65 Series suppressors are designed for the water
and wastewater industry. These multi-stage hybrid suppressors address
over-voltage transients with gas tube and silicon avalanche technology. In
addition, sneak and fault currents are mitigated with 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 Edco SS64
models protect a signal pair and the Edco SS65 models protect a signal pair
plus the cable shield (drain wire).
