What amp switch breaker?

Guys: I have two switch breakers that I need identified as to amp load. They are AMF Potter Blumfield units. One has the number 548-250-107 and the other has three numbers, 35-380132-9, 548-250-105, and a small number in the corner, 8231. I've googled the number and mfr, no joy. Any help would be appreciated, Dan from Reno
 
My guess would be to use the manufacturer spec sheet may help. The sheet I linked goes back to 2008 so if the breakers you have are older than that, maybe someone else can post an old data sheet.

If that does not help, you may need to test them to see where they trip. I would use a variable power supply with an amp meter. Unfortunately the variable power supply I have is only good for 5 amps.
