150A Fuse Holders Inline Circuit Breaker for Car Audio and Amps Overload Protection Reset Fuse Inverter 12V-42V DC Replace Fuses(150A)

This has a great look and stands up against an amount of heat resistance. The build quality seems like it will hold up for a while and was easy to install. The capacity held up to my 1000 watt amp with no issues. I cannot speak if it's waterproof as mine is mounted under the hood.

My mechanic that works on my boat suggested that I buy this circuit breaker with manual reset so that I can stop replacing fuses. He explained it to me that this will stop power surges from damaging my amps, and protect my trolling motor from electrical damage. It would also help stop over heating. It's been about a month and haven't had any real issues like I did in the past. From what I understand it is really easy to manage as well. If there is any problems I just have to press the on/off switch on the manual reset. Not an expert but I know that I haven't been blowing fuses like I use to. Price was reasonable, I ended up buying two to have a spare.

Got two of these for a car audio and power supply rebuild. I had the regular ANL 200amp fuse for my audio that was pushing two 12s and 4 vocal speakers (2 amplifiers) and decided to make the swap. I have not had power to the audio system yet but far as the other I use for the whole cars power source it works great. Done this swap so I could easily switch the breaker off and safely work on the car without disconnecting the battery. Works flawlessly. If someone is having issues with this breaker tripping, you are over the amperage. Looks to fit 8 awg and 4 awg fine.I use furells for my audio installations for these types of connections so the screw does not cut into my wire. It rather compresses the wire and keeps all strands intact! (Free audio tip)

Works great. Cuts power before your wires get hot

I have used these on several car projects. If you add a power cable, you need to protect them from shorts. These work well and can be opened to kill a circuit. Make sure you get the current rating that you need.

Needed to upgrade a 100A blade-style fuse that struggled to keep up with the power I've got running to my subs (2K RMS). Had a short in a newly installed capacitor and it tripped the breaker like one would expect. Resetting one of these is way more convenient than changing out blade fuses.

Bought this 6 yrs ago and it still works

It worked great until it didn't. I checked everything part of my 24v solar charging system and nothing made sense, until I put a meter on this. Maybe it did it's job or not.
