How to wire a DC breaker?

I hope that's right.

Anyone disagree with that determination?

Old thread but I didn't see this manual mentioned and thought it might benefit those that found their way here. I'm in the camp that these non UL rated breakers scare me and I do plan to replace mine soon. MidNite/CBI can be had for not much more money in the scheme of things.

Anyway though here is the manual that indicates supply (PV) at the top as you say but also claims that this breaker is "line/load reversible" and provides the diagram for source (PV) coming in the bottom (as is my case for example). PV from the bottom would be reversed, as is commonly marked on several other DC MCBs but not the Chtaixi.
