Maximum Peak Surge Current (all phases)


40KA

Maximum Clamping Voltage Level @ 40KA (all phases)


1650VDC

Start Clamping Voltage Level @ 1 ma (all phases)


430VDC


Accelerated Life Test

13KV, 1.2/50 usec. open circuit, 5.5KA, 8/20 usec. short circuit, 100 surge cycles, six seconds apart. No failure or arcing allowed.
Surge arresters still in excellent condition at end of tests.No arcing.

Temporary Overvoltage

Continuous, five minutes, maximum line voltage without thermal runaway.
368VAC

End of Life Failure Mode

While in overvoltage-induced thermal runaway, apply 7KA 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 wire opening.  AC line not faulted.  No arcing.
