Non-pullable or popable
Steve,
I just replaced one of these after some serious head-scratching due to a non-charging battery problem. I have this cb upstream of the bus and it was not popped so we "assumed" it was good and troubleshot a bunch of possibilities that included sending my plane-power alternator back for examination, testing the battery and all wiring, etc. Finally removed the cb from the circuit and found battery would charge fine. So I replaced it with the same cb and all is fine. I looked at the Klixon cb but they are about $100 vs $15 for the cheap white model. Since this cb had worked fine for over 2 years, I decided to stay with it and buy a couple spares to keep just in case.
