Curt,
This breaker is "Listed" with a note that it's short circuit current is 10kA and do not install it in the listed panels if they have more then 10kA available.

You, Me and the Inspector are going to need a magnifying glass to read all the panel model numbers listed on the side, I would say 50 to 75 different panel model numbers.
