CHTAIXI DC Miniature Circuit Breaker, 2 Pole 500V 63 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, Chtaixi DC Disconnect Switch C63

I used this with my off-grid solar array, and it works great. It arrived quickly and undamaged, installed easily, and so far works flawlessly (over a year so far). A little pricey, but worth it.

Perfect & delivery 🎯

Working as it should.

As another reviewer pointed out, the compression terminals don't hold a #10 stranded wire securely. No matter how hard you tighten the screws, the wires still pop out. I made it work by crimping a spade lug onto the wire, then mashing the lug with pliers enough to fit into the socket. A ring tongue terminal would also work. I also used a couple of extra screws into the DIN rail, on either side of the breaker, protruding enough to keep the breaker from sliding. If I need to remove the breaker I can just remove one of these screws and slide it off the end.

Good

I got one of these double pole breakers to disconnect the solar panels from the controller and to protect the whole system. Although I doubt two 100 watt solar panels could cause the breakers to trip, the protection is there if something does go wrong. The DIN mounting system is excellent: just screw the plate where you want it and the breaker snaps in place. The two poles means one can disconnect both positive and negative leads with one ganged switch. I mounted mine in a enclosed location and I just lift a cover if I need to disconnect the panels. Controller manufacturers recommend disconnecting the solar panels before disconnecting the battery connection to the controller, so something like these breakers are needed to do that.

This DC volt breaker is so much better than fuses. This was a nice upgrade on my RV,s solar generator.
