What's the difference between these two GE AFCI breakers...

I got a AFCI breaker from an electrical supply house and I compared it to what was at the box stores. The one from the supply house is THQL1120AF2 and the one from the box store is THQL1120AFP2

I can't find any info on GE's website. The one from the supply house is $46 and the one from the box store is $34. The picture on GE's site looks like the one from the box store. Does any one know the difference?

It is hard to tell just by looking at them. The model numbers will let you know if they are approved for your panel by looking on the label on the inside of your panel door or can. If your panel has the cheaper breaker listed then go ahead and use that one. The performance of the two breakers will likely be the same.

They are both Type THQL breakers so they will fit the same panels. I think all you'll ever find is that the "AFP2" breaker is blister card packed for retail sale in hardware and big box stores and the "AF2" breaker is packaged in boxes for wholesale trade. The difference in price is likely due to a retail sale at a supply house that discounts only to their wholesale customers versus the big box discount.

But they are physically different in appearance.. One is grayish and one is black.. One has a rocker like test switch and the other is a button.

Here is one that's the same, it's black and has the blue test button like the "AF2" breaker. Scroll to the bottom of the page and click on the breaker to get a better picture.

Shop Laundry Room : Electrical : $25 - $50 : GE at Lowes.com

They both fit the same applications. The rocker switch is likely an older design and older stock.

Well as long as they are the same on the inside... I'll return the one from the supply house and get the ones from the HD/Lowes!

The one at the big box store seems to be one intended for consumers, while the supply house one is made for ec's. I also saw gray ones like that in my buddy's house built in 2003.

GE makes two TYPES of AF breakers...the THQL1120AF which is the original arc fault and the THQL1120AF2 which also monitors the ground (not a ground fault)...is the newer style and it is referred to as as a combo arc fault because it monitors more than one type of fault. That being said.....The only difference in your numbers is one is plastic enclosed for retail. They add the P for that. GE has breakers made in USA, Singapore, and Mexico. So color will vary. We ordered several hundred THQL1120 some time back and half the breakers were made in Singapore and were lighter in color, the rest were darker and made in the US. Such is the ways of a global company.....
Bottom line - those are the same breakers you are looking at in the pics.

manufacturer differences

The black breakers have a Seimens/ Murray mold and are manufactured for GE. The gray breakers are manufactured by GE. There should be no difference in function. The "P" describes the packaging, no difference in function.

The breaker from the SH is Switch Duty Rated,I don't believe the others are.

Other difference is that the grey breakers are likely a "mod 3" version that lacks the 30ma GFCI. This lets you use them on MWBC by adding a handle tie.

"MOD 3 breakers are easily distinguishable by their gray cases and black test switches."

Interesting observation, it does appear to be a Siemens Type QP molded case. We don't have a similar view of the gray cased breaker. I know that Cutler-Hammer used to make some GE breakers 20 years ago with the CH series bolt-in mold so I wouldn't be surprised that Siemens also has made some for GE. For what it's worth, Square D has built some GE pad mounted switchgear for years.

"MOD 3 breakers are easily distinguishable by their gray cases and black test switches."
I see the black breaker with blue test button is a MOD 2, probably an earlier version before GE began building their own AFCI breakers.
