We're talking about two panels:
- #1 the panel you asked about in earlier questions which is Eaton or predecessor.
- and #2 the new panel you just linked which is Eaton.
In both cases, you must use Eaton BR breakers. You must use breakers UL-listed and approved for the panel. Breaker panels differ - to avoid patent infringement they all made their bus stabs and clips slightly different, and the wrong breaker will have poor bus stab contact and will arc and damage the bus stab... so breakers are NOT compatible across brands even if they appear to fit.
This might seem anti-competitive, but it's not - breakers are reasonably priced, even compared to Europe's "open standard" breaker systems. Unless they're Square D "QO".
In fact, competitive pricing is why your only choice is Eaton. UL permits competitor breakers, and will mark them "UL-Classified" when they are certified safe. Square D "QO" overpriced and as a result both Eaton and Siemens make UL-Classified breakers for QO. Nobody else makes breakers UL-classified for BR, because Eaton doesn't repeat Square D's mistake - they price their breakers very competitively, leaving their competitors no airspace on price!
What type of GFCI/AFCI combo breaker should I use?
"BR type".
What brand of GFCI/AFCI combo breaker should I use?
Eaton, unless someone else wants to lose money trying to compete with Eaton with a UL-Classified breaker for BR.
What spec of GFCI/AFCI combo breaker should I use?
That's a good question. I'd get the most modern type, which has an electronic control giving an LED readout as to exactly what the previous trip reason was, and also has electronic detection of overloads for better performance.
Regardless, buy ONE such breaker. Bring it home. Test it on each circuit one by one.
That is for two reasons: #1 confirm that the breaker will physically fit inside your panel, as I discussed in the other question; and #2 to assure that hooking up the circuit won't instantly trip due to some faulty wiring or defective appliance. Thus, test-fit the AFCI/GFCI breaker onto each circuit one at a time, checking for all that.
