ZOOKOTO 12V-24V DC Circuit Breaker 200A, Trolling Motor Auto Car Marine Boat Bike Stereo Audio Inline Fuse Inverter with Manual Reset with Waterproof Cover

I use it as a disconnect for my solar panels. The fuse is an added bonus. Was easy to install, I put 10 gauge wire at both ends... I think it was a T5 torx head... But seemed like a good solid connection that has nice insulated screw on caps with rubber garments to help keep dirt and water out of the connector. I wouldn't want to try putting anything bigger than a 10 gauge wire... tho, maybe you could go 8 tho, doubt the rubber end caps could be used.

I purchased these breakers to isolate my RV house battery and solar panel, they work great with the push button cut off a nice feature. Recommended.

I ordered two of these, tested it and it initially worked almost as specified. It would trip at about 180 amps which is pretty close to 200 amps so I was happy. I ordered another and it tripped below 100 amps (it should have tripped at 200 amps). I sent it back and got yet another. This one tripped at just over 100 amps. I decided to keep it since I had a use for a 100 amp circuit breaker.Update: After using this for a while I found this trips well below 100 amps and that's totally unacceptable. (Note, it takes a while before it trips but after five to ten minutes it trips at much lower currents.)

I installed this in line with my radiator fan and so far have had no issue. I tried the breaker function and it works fine. It's a sturdy little unit and the four attachment holes allow it to be mounted easily. The wire mounts come with clear plastic covers to keep the terminals clean and dry even in areas where they may get splashed with road water.

Very nice product. Allows different sizes of wire. Allows you to switch off the circuit manually or use as a circuit breaker. The connectors are insulated by clear covers.

I ordered 2 of these Zoocoto inline 50 AMP circuit breakers for a project. When I was able to get to that project and wire these in for a less then 50 amp circuit I found the first one would randomly pop. I tried the second one and it was worse then the first one popping almost immediately. These certainly will not hold 50 amps. I had to get a different brand and that one is working as it should so the problem is in these circuit breakers - not in the line. I'ts too late to send back even though they did not go into service until last week.

This breaker appears to be built solid however, the reset button doesn't work which defeats the purpose for the breaker! I contacted the company which sent me another. The replacement one works perfect and I would buy it again.

I bought three of these in a short time period two 100 amp and one 150 amp used the two 100 amp on my dual battery set up on my truck and the 150 to replace a blown fuse n my wife's car stereo amp. These are super easy to install. And will fit many different size cables with the supplied adapters.
