100Amp Waterproof Circuit Breaker 30A-300A Auto Car Protection Inline Fuse Stereo Switch Fuse Holders Without Fuse Replacing

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.

The unit seems like it's good quality, and it was easy to install. I can't vouch for the waterproofness, but that looks good visually. I use the push button whenever I need to service my system for any reason. To re-connect you just flip back the little yellow lever. Nice!

Sheerness and thickness of a circuit breaker? Amazon really needs to check the adjectives they use for item descriptions. Anyhow, fast shipping and it should work fine on the wiring for my new trolling motor.

Excellent price for product.

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.

No complaints. I believe this breaker will work as designed. I'm using this breaker to protect the circuitsat the helm.

As others have reviewed, this breaker does not work to its specified current rating. Installed in my RV to protect my inverter/charger rated at 2000 W/ 80 A. First problem I had was attempting to run a microwave. It popped 30 sec into the cook. Even if it was pulling the full 2000 W, the DC current spec limit would be about 190A, well below the rated 250 W of the breaker. But it got worse. This breaker finally would not even let me charge the batteries at 80A without popping. ONE STAR IS VERY GENEROUS. Not worth the plastic it is made of an definitely not worth the advertised and paid cost. I now have a paperweight.

Used this circuit breaker for my power inverter and haven't had issues with it. I do wish it had some thicker terminals but not complaining. When it did rain, it didn't short out or cut off power for my inverter.
