When you disconnect DC, there's an arc that must be quenched. The breaker is only designed to do this in one direction. (Battery is line)

Several breakers are dual rated. You just have to verify the ratings for your use.That's good to know, really wish the breaker had the DC info listed, seems lots of companies sell this but not a bit skeptical since never seem a AC/DC breaker

Charging amps are far lower than fault amps available from the battery. And that isn't a polarized breaker.So I just did some reading, seems that ppolarized breakers are only safe in one direction, if using an all in one inverter like growatt then this breaker should not be used because When charging the breaker will not extinguish a spark/flame. Now not am I more confused but also frustrated that I can't seem to find a good breaker for my AC in

Line and load identified is directional.
Positive and negative identified is polarized.

Positive and negative cables don't need to be the same length. Same length only matters with parallel cables.I cant mount the breakers properly and keep my positive and negative cables the same length, unfortunately I can't mount the breakers horizontal so probably need to go with fuses like my original plan was, I liked the option of multiple trips but looking like a 110 amp gopower class T os my only option if I want to keep my wires the same, so frustrating and irritated right now
