A 2 pole for 220V loads would not be required per 210.12. However a 220/120v load , i.e.-multiwire circuit would require to be protected via what I understand is an AFIT ( type of AFCI) , made for multiwire circuits and a dif animal than a straight 220V 2-pole AFCI.

This is what i've been looking for, especially in a larger ampacity, 40-60A .
So far I have had no luck finding one. [Linked Image]
