The Siemens FS-250, with optional 3a transformer, can handle 6A total. The four NACs are set up in a class A configuration(two NACS). The cut sheet says 1.5A per nac, max 6a. In class A configuration does this mean it can deliver 3A on each circuit?

I think the answer is yes. I'll contact tech support on Monday to verify. If this panel is being used for releasing, you'll need the second optional transformer as well.
