Thanks for your thoughts Z.

Memshield 3 catalogs give a "conditional short circuit" rating, the Memshield 2 series does not. I could make some assumptions about the cross sectional area of the busbars themselves based on their rating and using the equation in 434.5.2 compare with the energy of the downstream MCCB energy let through. All this sounds good but it could differ from reality - client might not like it but its worth a try.

Also sent Eaton technical an e-mail, lets see what they come back with.
