Thank goodness for Amazon shipping being so fast - our solar power system was dead in the water without this!!

Uses 4 spaces in breaker box for a single circuit protection/hot switching. Jumpers are used to connect multiple breakers in series to allow switching higher voltages. Diagram on breaker shows connections.The indicators show RED when the circuit is ON, Green when it is off - different than other breakers I have used.

We have a pavilion with a mini pv system and are using this for our 'dc' load branch. This is the exact size that I was looking for in the form factor I was looking for. I have been switching things over to use the DIN mount system and love how easy it is to install and modify systems using those mounts.

I am using this as a solar disconnect switch and it works for that.I have no way to properly test whether it will trip at the rated current or not but this is one of the few budget brands that I’ve watched people who have been able to test that, did function as it was supposed to. So if the need ever arises, hopefully it will function in that regard too.

got this to use as the main disconnect or my PV system on my cabin. Works as expected and works fine.

Pretty standard mini breakers for DIN rails. They seem well made. Plus, I appreciate actual specifications in the product listing!I became interested in CHTAIXI brand breakers after noticing them in several builds on various YouTube channels.I ordered this for the solar disconnect near my solar charge controllers. I have two strings, both under 150 volts. Unfortunately, I didn’t notice that this was intended for a single circuit, not a pair of them. I’ll hang on to it for a future project.As I said initially, it seems well made. It has a good heft to it and the action of the breaker is nice and crisp.

If you're looking for a reliable DC Miniature Circuit Breaker for your solar PV system, look no further! This 4-pole, 50 Amp isolator does an outstanding job of protecting against overloads and short circuits. With dimensions of 2.95"D x 2.84"W x 3.17"H, it’s compact enough to fit in your setup while still providing robust performance. The flame-retardant shell and silver alloy contacts are signs of solid craftsmanship, giving you confidence in its durability.On the downside, installation can be a bit of a puzzle, especially if you're not familiar with DIN rail mounts. It requires some careful handling of the wiring, particularly with soft silicone wires that need crimping first. So, if you're not technically inclined, you might want to have a professional help out.That said, this circuit breaker delivers great value for money, ensuring your system operates smoothly while keeping you safe from potential electrical hazards. It's a must-have for any solar enthusiast!
