PMT3 Series - Three Electrode Heavy Duty Gas Plasma Arresters
This series (150-500V) is primarily used for the protection of telecommunications equipment in which simultaneous crowbar action of two signal lines is required. Comgaps function as switches which dissipate a minimum amount of energy and therefore handle currents that far surpass other types of transient voltage protection
