Ray,
If you have, it wasn't correct. The CFs are 1" wide, the QOUs are 3/4", and the mounting holes are 1" apart. Are you sure?
The CFs have a 125 VDC rating.

I've seen both on the DC side.  The QOU also had a high VDC rating (125 v as I recall).

Ray,
The AC breakers were SqD QOU; the DC were Heineman/Carling/Airpax CF series.

I thought the APT panels had Square D QOU breakers?  Also Midnite makes an adapter plate that lets you use a newer panel mount DC breaker in the place of the old medium Heini breakers. Might not help there.
I added an MPPT controller to an APT center a couple years ago, and I just added a small secondary breaker box, because I didn't have right size QOU.

Friends:

I am adding an MPPT charge controller to a functioning APT power center. I
need one breaker for the job. The breakers are like those used in the Trace
DC250 cabinets but surface mount. Where do I look for one of these, please?

Thank you very much.

William
