ANJOSHI 50Amp Waterproof Circuit Breaker 30A-300A with Manual Reset Suitable for Car Rv Marine Automotive Stereo Audio Electronic System

This thing is awesome! I have factory breakers installed in my boat but have never seen them like this before. I had a customer come to me to get light bars and an auxiliary fuse block added to his 2019 Polaris Ranger. While the fuse block had its own fuses I wanted to add an inline fuse to the fuse block as well since the power wire would be running just above the plastic skid plate near the drive shaft (where all the factory wires run) and I knew he would be using this in the West Texas Hill Country with a ton of sharp and jagged rocks. So in case anything should happen while out in the middle of no where I wanted to fuse this main power wire close to the battery. While searching for fuses I found this breaker and immediately thought this would be a good idea to be able to fix an issue and reset out on a trail instead of having to carry spare fuses or even possibly having to order one of the fuses online and waiting several days for it to show up. These are awesome and I will definitely be purchasing these for more jobs as they come up.

Installed between my RV convertor and battery bank. It worked fine for about 2 months. However, I had to charge my batteries using my generator and noticed I was getting very low amperage and voltage output to the batteries. I thought it was the convertor, but a quick check with the multimeter showed me full convertor voltage of 13.3 volts on the convertor side of this breaker, and battery voltage on the other side. It was allowing....some....current through, but not much. And, yes, this was in the engaged/active circuit position. It worked the same, even after cycling it a few times. I took the power lead from my convertor and joined it to the battery bank lead and got full voltage and charging amps to my battery bank. Lesson learned for me. I tried to save a few bucks over what I'd pay for a similar Blue Sea breaker and it let me down. This is going in the garbage, and I already have a Blue Sea breaker on the way.

used it for on top of battery box to protect trolling motor and as a cut off switch. It works but is far from 60A it claims. It popps at just over 45A draw within 60 sec. Is a good thing I keep plyers with me and was able to move one wire to get my self back to the dock. So back to the drawing board. I will leave it for a cut off but have to find a REAL 60A breaker that will hold and not kick off at only 45A. Also the wires, terminals or heavy power poll were not warm. I have a Amp meter in line so sure of the draw.

I originally purchased this to be a battery circuit breaker for my truck's winch. I opted for the 300A version because the winch has a max draw rating about that much when under its max load (which I'd never push it that hard ever).I received this breaker today and was immediately disappointed with its poor quality. I quality checked it with a tester in my lab before trusting it on my truck and it really underwhelmed. I thought I was being clever saving $65 going with this instead of a BUSS-brand, but instead I'm just returning this and applying that refund toward a American made BUSS instead. This thing exudes cheesy Chinese made junk. Unless you have a lower amperage solution, this won't last the test of time and has serious safety concerns.

I built a whole charging system for my van, solar, dc-dc charger with 600Ah lithium. This breaker is between my battery and my distribution bar. I was seeing weird voltage swings +/- 5 volts when It was under load. I woke up and nothing was working. Thought I had fried my sola controller or the batteries. After chasing it down with a voltmeter- this breaker stopped working. Sometimes it out our 3v. super weird. I purchased this because I didn't want to replace any blown fuses out of laziness. I'm going back to the standard AMG fuses.

I used this to be a battery isolator switch in a solar generator project on a 12 volt 100 amp-hour battery, between the battery (+) and the + terminal on the 1500 watt pure sine wave power inverter. Works just fine for that - and I hope I never find out if it works being a circuit breaker, too...

Great protection for added hi amp wire to winch. Mounted close to battery to protect downstream wiring from short. Like the on/off switch to cut power when working on the circuit. UTV winches take 300 amps.
