Data/Signal Line Protection

Edco COHP Series

Data/Signal Line/Punch Block Protection

High Exposure Applications

The Edco COHP modules are three-stage hybrid protectors for low voltage data and

telecommunications applications. The modules address over-voltage transients with

gas tubes and silicon avalanche components. In addition, sneak and fault currents

are mitigated with resettable fuses (PTCs). Intended to be used on pairs without

the presence of ring ing voltage. The Edco COHP modules are designed for data and

control applications as an isolated loop circuit protector.
