I would trust Current Connected to vet products. Amazon is the Wild West.
The imo type disconnects have a spring loaded design so when switching off it does it at a fast rate. If you were to slowly trip a DC breaker you could have issues. It seems best practice is an imo disconnect. I went with this dual circuit version from Amazon but who knows how it compares to the "real thing". Other choice would be Midnite solar DC breakers, great reputation, fully rated, maybe in a midnite baby box if you need a metal enclosure.
Those are what I have been using. They work great for my arrays. And I have put them through a lot. With zero issues or failure.
I am using this disconnect at the advice of the AltE store. I have 12 360w panels in series so there aren't any breakers that I know of that can handle that type of voltage.
Midnite have a 600V DC breaker series but not cheap at $152.
Thanks. As I recall my disconnect was $95 and it's the heavy duty spring type disconnect.
I have these and the only issue I’ve found with them is the terminals. With course stranded wire, thnn 10 awg, the wires can be pulled out. I’ve tried ferrules with the same results. The only thing that works to my satisfaction is to strip back the wire double of normal then fold back bare part in half. Orbit the wire gently as you tighten the terminal screw. Check back and retighten in a few days. Time loosens wire terminals. The only point of failure with these breaker are the terrible terminals and loose connections will destroy the breaker or worse. All the plastic DIN breaker boxes that are sold on Amazon for these can burn with enough heat so use a metal box . I suggest using what the others above have recommended unless you’re diligent about tightening.
Why did you choose a breaker over an “IMO” type switch?
The one current connected sells accepts up to 8g and stranded only.
Cost, size, and installation compatibility.
I would recommend stranded, for this type of terminal. But I have had solid #12 connected to them for over a year.
Without checking the specs. My eyeballs say that #6 stranded will fit in the terminal.
I have around 50 of these in my system, no issues at all. But I have the same brand in 125a breakers for my aio, and batteries, and I have had at least 3 failures in the 30 of these I have.
