And also factor in many manufacturers count each protection mode
seperately to arrive at that number, eg if it uses MOVS rated at 20KA
and there is one from L1 to ground, one from L2 to ground, one L1 to
L2, that makes it a 60KA rated device. Meaning that 100KA one is
likely really 33.3KA.
It also shows that on the granger site. I think what happened, the earlier
model was superseded with the 150k unit, but they got the data sheet wrong
or not updated.
I had the lesser rated unit, and it blew. These things are warranted, so
keep all records.
