wohhom200 Amp Circuit Breaker with Manual Reset 12V-36V DC Waterproof Surface Mount for Car Audio Rv Marine Boat Truck Trolling Motors, 30-300A Car Speaker Resettable Fuse

Used this instead of a fuse for an auxiliary fuse block that I added to my Jeep. Used a Blue Sea fuse block and was impressed by the quality, so I got their circuit breaker too. Good quality unit, the rubber caps for the studs are a nice touch. The best feature is the red button that lets you manually trip the breaker. Intended for marine applications, have had no issues with it on my Jeep for the past year, and can't imagine I ever will.

This is waaaay better than getting an in-line fuse.You NEVER have to buy another fuse again, because it has NO fuse .Also, you can cut-off the power to you amplifier, if you need to adjust your cross-over sound settings for your mid-rage and high speakers.My sub is a 15-year old Infinity BassLink. And I am running it with a Pioneer AVH NEX-2550 head unit. My stuff is BANGIN' HARD now. This is because the 30-watt blade fuse I originally had under the hood was weak and restricting proper flow to my amp. With this breaker my 15-year old sub sounds waaaaay better. I never new it could BANG that good. And sounds cleaner too.===========INSTALLATION was a breeze.1) - UN-hook just the positive cable and put the terminal on a cloth so it does not touch any metal by accident2) - Strip about 1/2 inches of the protective sleeve off the Audio cable for both the ends that will go into the Fuse Breaker Switch3) - Jam the wire as far as it will go into both ends of the breaker4) - Screw down the wire cables with an allen-wrench.5) - Make certain to have the clear and red protective caps screwed back on for a water-tight seal6) - NEVER, EVER install this breaker close to your amplifier.You just need to install it as close as you can to the car battery. About 6-inches of cable or so.7) - For SAFETY, I made certain to have the breaker switch in the "OPEN" position BEFORE I attached it to the battery terminal.8) - Connected to the battery terminal. Turned on the car and radio.9) - Closed the breaker switch10) - Viola!All done, son !!===========ADDITIONAL NOTES :For my 200 Watt amplifier, I got a 40 AMP.IMPORTANT: Make certain to get just the right amp amount that SAFELY matches particular wattage of your amplifier.NOTE: Purchasing too high of an Amp for the breaker is like having NO protection at all.Hope all this helps.

put this inline on my solar install. I needed a switch between the controller and the panel, plus this gives me voltage protection. so rather than by a fuse and a switch, this does the job perfectly. You never want to remove battery connections without disconnecting from solar, or you will burn up your controller.

I built a so called "Solar Generator" and needed some added protection. This 70A DC breaker was installed between my 1000W inverter and the bus bar (distribution block) with 4AWG cable. It was easy to install and gives me piece of mind. It also serves a second purpose. If I am not using the inverter, I turn it off and then trip the breaker to ensure that no power at all is going to the inverter.This added protection is worth the extra effort and the breaker is a terrific value for the price. It is good quality, works well and does trip when overloaded. I tested it 3 times and it just works. Reset takes about a minute when it cools down. I can easily recommend this breaker and I give it 5 stars.

Good product my only complaint is that the holes for the set screws strip out very easy. so be careful not to over tighten the screws

This was supposed to help me not go through fuses so much and that it does. But the problem with it is that it’s cheep. I’m running a Rockville RVA-M3 4000w Peak/1000w CEA RMS @ 1 Ohm Mono Car Amplifier. On the amp it has 3 40amp fuses. If I’m running my system hard I get about 4 min in tell this breaker trips. Then it’s about a15 min wait tell I can get it to stay engaged. Have never blown any fuses in my amp totaling 120amps so the 150amp should hold up but it doesn’t. I suggest if you buy a cheap one like I did make sure you over do it. It’s only really there to protect from a short. I will be upgrading soon to a 200amp.

I had to decide between 30 amp fuse or a 30 amp breaker. I chose a breaker and very happy I did. I have one installed between my solar panels and my 30 amp charge controller and one between the controller and my batteries. I mistakenly disconnected my batteries from the controller and then went to reconnect with the solar panels already connected and instead of burning my controller or blowing a fuse which would have cost money it tripped the breaker and all I had to do was manually trip the breaker on the incoming solar positive and then reset the battery breaker and then the solar breaker. I explained all of this to show how useful and practical a breaker is. These operate correctly at a decent price.

The media could not be loaded.  There are a lot of ways to protect a circuit in your vehicle, and the most basic one is a fuse. I like breakers like this one because they give you the option of keeping the circuit off when not in use, kinda like a switch.Power in on one pole and out on the other. It's that simple. Note that these are not all the same: this one is rated at 30 amps for tripping, so you gotta know what's on your circuit to size your breaker.
