UTSAUTO Circuit Breaker 150Amp Resettable Fuse Circuit Breaker Auto Car Stereo Inline Fuse Holders Inverter, Manual Reset 12V-24V DC for Automotive Marine Boat Audio System Protection

Installed because I had went through multiple regular fuses. I think I have only ever had to reset it once, if I remember correctly, due to my own negligence. Saves a lot of money being spent on regular fuses, though!

I like to combo isolators and breakers over fuses for primary battery & charging side main and breaker along additional batteries, generally switch to fuses at the distribution but considering busbar and back to breakers I dont go through fuses very often, but when one does go it's always at night, with no light, and seems to have scared off any replacements thought to have had . To the point of not blowing fuses often, perhaps burning is more appropriate. I had a buddies car burn down from a fuse block not being properly installed within all of 2 minutes from starting the vehicle. He made it nearly to the main road before the whole driver side of the car was up in flames, He having to open the door and jump through the flames erupting from under the carpet where the writing was laid. There was a second battery in the trunk with both power and ground lines connected to the primary battery to eliminate noise in the system. Originally everything had been fused to ensure those lines would be safe, but some audio expert at some point told him he didnt need it fused as it were. He removed all the fuses and reinstalled only 1 fuse block without anything insulating the block bottom and left dangling along the main. The mains such that they were, were too close to the turbo and had melted to bare copper. After the guy had improved the system tto randomly cut off and also improved upon the resolved noise issue through amplified reintroduction of it, my buddy came by to have me look at it again. I immediately noticed the mains melting and as a quick fix painted them up with some liquid tape and taped them. The mains having been so severely melted that I missed noticing the block dangling and exposed. In fixing and relocating the main, the block must have found the right spot to be in to sit on a short. It didnt take long that before the short caused both 0 gauge power and ground lines running between primary under the hood and secondary battery in the trunk to heat up til aflame the full length of each. If you have never had an electrical fire, here's a word of advice water will not put it out, nor will an extinguisher so long as the power source is still feeding it. It took another 5 minutes before someone came and told me the car was in flames and foe me to get there at which point he and a good samaritan turn from the the smoking car to me they just got the fire out. Black smoke pouring out from it seemed to say otherwise at which point flames come shooting out the open driver's door from under his dash to which he then pours half an 8oz. bottle of water on to no avail. Luckily he had popped the hood when he saw smoke coming from it originally, and the trunks electronic pop had shorted opening it allowing us to rip out both batterys. The battery terminals had melted with the connections to them seemingly welded with the batteries catching fire but none the less still putting out juice andufeeding the fire til they were torn from the vehicle. It burned hot and fast cooked the entire electrical system of the vehicle. So I switched to breakers and havent friqused any more of Germany's Farfegnugen. 2 point advantage to breakers.

It was delivered exactly as expected. Seems like decent quality materials.

I like everything about these breakers. What happened was the 150 was listed but I changed it to a 20amp. The order was sent with the 150 amp so I had to reorder 20 amp breakers and send the 150’s back. No problem, everything went fine.

Went through a total of 6 breakers including the square body version and had bad connections internally. Couldn't get the truck to turn over and even the ACC mode would not work which requires very little power. This was going through dual channels of 1/0 oxygen free pure copper so both circuits failed(multiple times (it was rebuilt)) which should have protected me from one failing. Eventually figured out these relays were not going to work. Switched to a ANL fuse and haven't had any issues since. I soooo wanted these to work which is why I tried many times. Rust was not an issue as these only lasted maybe a couple weeks not months but even then. GM will rust out for decades before failure.

It was easy to install and insulated very well

A+++++++

Works good for its use. Easy to install. Functions as required.
