Probably some of you already have seen these but I had not until now on Amazon while looking for a 30a din rail AC breaker. About twice the cost of the Chinese mini breakers but I would trust the Westinghouse name much more. They are rated for the 1 pole at 277vAC and 60vDC and the 2 pole 480Y/277v AC and 125vDC.
So if you would like the din rail format, and want a US brand with UL 489 listing, it might be the ticket for you. https://www.amazon.com/Westinghouse...66&sprefix=AC+din+rail+br,aps,291&sr=8-7&th=1
