ANJOSHI 300Amp Circuit Breaker 30A-300A with Manual Reset Switch Waterproof Fuse Holder Inline Fuse Breaker for Trolling Motor Auto Car Marine Boat Bike Stereo Audio System Protection

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.

Initially the product seemed good it worked as intended. I used it as a breaker for my winch. However a little over a month later I go out and want to use my winch on my property and the winch doesn't seem to be working. So I grab my volt meter and power is going into the breaker but no power comes out. I reset it a few times and I notice the tiny reset lever is offering almost no resistance when putting it back into the set position. Unfortunately I dont know exactly when it went bad because I don't use my winch that often but now it is outside the return window. So I'm just out the 25 bucks. But thought I would share my experience on the matter. It's very possible I just got a bad unit, because I saw all the good reviews about it which is why I went with this one.

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.
