The Panamax MOD-CAT5 is an add-on signal line module for Panamax protectors. Some Panamax protectors offer a screw in spot for these modules, others require making a small grounding cable to attach to a ground lug. The MOD-CAT5 provides protection for a Gigabit Network cable (CAT5, ATM, Fast Ethernet, etc.). The input and output sides of the Panamax MOD-CAT5 are hooked up via the integrated network cables. The clamping level is 19 volts, all pins are protected.
