End of Life Failure Mode
While in overvoltage induced thermal runaway, apply 7 KA at operating voltage. Surge arrester must fail safe without faulting the AC line. No arcing allowed.

Surge arrester fails safe– surge element punctures, safety fuse opens, LED turns off, no fire, slight puff of smoke out connector wiring opening. AC line not faulted. No arcing.
