Good going John, I looked all over tarnation and couldn't find squat on
those things.

I found a place with a bundle in stock however.

My old Seimens datasheet shows that to be 145 VDC +/- 20% breakdown, 
<750 V impulse breakdown (100 V/us impulse) and <1100 V impulse 
breakdown (10,000V/us risetime impulse). It can handle 5000 amps for 
a single impulse, with approxiamately 200 shots before failure. Its 
AC current rating is 20 Amps RMS when first breakdown (for 11 
cycles), discharging 35 amps followon. It should extinguish on the 
next zero crossing, so this is only usually 1/2 cycle or so - unless 
it is grossely overdriven. It is specifically made for AC 
applications, like across AC power circuits for protection. Things 
like CATV amplifiers and remote 24VAC systems outdoors, that have ac 
power feeder.

As far as knowing the gap measurement, or material, it doesn't say. 
It has some 'rare' gas inside but not radioactive as far  as I can 
tell.  Why do you need to know those parameters?
