I checked and even though there is zero mention about the panel mount breakers being polarity sensitive or otherwise on the product page:

Ryan says in the video, that they arent polarity sensitive.

Thanks for posting those links, you're right the panel mount breakers aren't polarity sensitive and they are also suitable for AC & DC, however the DC din rail ones are polarity sensitive. I have 5 of the 150 volt ones for string protection so will be mounting them according to the instructions.

Hey that wing nut looks familiar

The Panel mount breakers are not polarity sensitive. They do have a line and load but that I am told by Carling has nothing to do with DC and nothing to worry about
