This is great I have spent so much time trying to explain this to people a picture is definitely worth a thousand wordsI searched the forum for this information but could not find it, so I'd like to post this file (if that is acceptable).

Thanks! C65H-DC is exactly what’s printed on the front of mine, so from what I gather, you’ve got yours wired the same way I propose to wire mine?I'm not the smartest guy in the room when it comes to breakers. I already goofed up once (or twice) on buying the wrong breakers. So take this with a grain of salt...
@Sverige, I'm not convinced that the breaker in your picture is polarized. Does it actually SAY that it is polarity sensitive? I have a set of single pole breakers that are polarity sensitive and they get wired with the battery feed on the bottom and the load on the top.
I have a set of C65H-DC double pole breakers that appear to be polarity sensitive (the label is a bit vague). I have them wired with the feed (solar panel) coming in the top and the output (to the solar charge controller) going out the bottom, following the + and - labels that are on top but not on the bottom. I have thrown the breaker to test cutting off power to the solar charge controller and it worked fine - no magic smoke. Then again, maybe I just got lucky.
Check with your manufacturer's instructions. Yours may be different than the Altech in the document provided in the original post.

Can someone explain why you'd want to use a polarized circuit breaker to begin with?
Arc Chute (gesundheit! ... see https://diysolarforum.com/threads/setting-up-a-dual-pole-circuit-breaker.14458/post-161475)Can someone explain why you'd want to use a polarized circuit breaker to begin with?
Holy crap.. video showing what happens if you wire those polarized DC circuit breakers in reverse and try to turn it off:
Thanks for posting this! I’ve been looking at this breaker I bought from amazon, trying to figure out how to connect it between my PV panels and charge controller, and with the help of your diagram I think the correct answer is as follows:
top left terminal to PV negative
top right terminal to PV positive
bottom left terminal to SCC PV input negative
bottom right terminal to SCC PV input positive
correct??
