  • Model: CHFN120A1CS
  • Description: Eaton CH arc fault / ground fault circuit breaker, All-In-One, 20A, 10 kAIC , Single-pole, 120V, pigtail, 3/4" AFCI/GFCI

I bought two of these breakers and they both behave exactly the same. They both seem to work properly. They shut off when I test them via the button on the breaker as well as trigger a ground fault using a testing tool.

The main thing that concerns me is that when I flip the breakers ON, the LED light quickly blinks just once. According to the instructions it seems like it should blink 3 times very quickly (within the first half second), indicating that the circuit board is protecting on 20amps. (1 blink = "Uncommon", 2 blinks = 15a, 3 blinks = 20a).

I can't seem to find the same instructions I have online for some reason.

Is this a problem? Is it protecting as AFCI and GFCI? Am I misunderstanding the instructions?

Here are the paper instructions, since I can't find a link to them online:
