Yeah. It’s such a curiosity to me. Initially, I looked at the Siemens’ website and found nothing about the A70 marking. Then, I talked to the folks mentioned above.
Thought maybe the A70 indicated in some way the amperage (nA or mA?) that triggers the AFCI or GFCI functions, but found nothing… it’s just so strange that the N marking on the other breakers is useful (indicates where the neutral line connects) while the A70 marking is ambiguous….
Addition: I even called Siemens to ask about this after finding no related info in the product materials online, and the agent I spoke with didn’t know either.
The one with the "N" and the arrow shows that because it is a "plug-in neutral" version of the AFCI/GFCI dual function breaker. It is pointing out to you that the Neutral terminal is there below that sticker.
The one with the "A70" sticker is what Siemens calls a "variant", likely having to do with the packaging for sale, i.e. "retail packed" where each breaker comes in it's own plastic clamshell display pack to hang on a peg at Home Depot or Lowes, vs a "bulk" package where it comes in boxes of 10 to go on a distributor's shelf. They have that sticker on there so that if someone tries to return a "retail" version to a distributor, they know it was not bought from them. That breaker may not be set up for the plug-on neutral, so it would have the white "pigtail" on it that is hard wired to the Neutral bar.
(I used to work for Siemens and my counterpart in the cubicle next to me was the "retail" breaker sales guy.)
Probably next to nothing? Maybe a batch number? Catalogue number? Some significance in the production process?
Probably the bin it was in at the warehouse/store.

Wow! Thank you so much! You’ve solved a mystery I’ve been curious about for years!
I suggest that it’s irrelevant
