I have done a few of these systems, and with the exception of one pre-packaged unit, I have simply mounted my contactors in NEMA-1 pull cans, as shown by Larry. There has not been any questions raised; I see no code, or UL, related reasons to require the use of something with a hinged door and separate rear panel.
Not that I will fault any place for having their own local ammendments. I would just want to see the local ammendment - and not just take someone's "construction" of the rules. Ditto for whatever issues may arise as to the accessibility of the panel.
The pre-packaged unit I recently wired was designed so as turn the exhause fan on when the system trips - even if everything is turned off. I will not criticise this design, only point out that I do not see any code requirement for this operation.
