The 17690X series replaceable Gas Capsules are designed
for a high degree of surge protection. It operates on the
gas physical principle of the highly effective arc
discharge. The 17690X series is used for protecting
equipment for which higher voltage limits and holdover
voltage are necessary. These gas capsules are for use with
the Benelec 176210 Lightning Arrestor. 176210
