Data/Signal Line

COHP modules are three-stage hybrid protectors for low-voltage data and telecommunications applications. The modules address overvoltage 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 ringing voltage.

COHP modules are designed for data and control applications as an isolated loop circuit protector (UL 497B).
