Hamolar 3 Pack Car Audio 150 Amp Resettable Fuse Circuit Breaker Car Protect for Audio System Fuse 12-48V DC for Car Audio Amps Overload Protection Fuse

Works great

Great product and significantly better and easier than dealing with traditional fuse holders.

They’ve held up well and really like the disconnect feature, easy to install. Definitely recommend.

These breakers work as designed and promised, but will fatigue and crack over time, faster depending on your application. In my case, I use them to shut off power to a winch on a truck and it's mounted in a hostile environment under my hood. I get about a year out of each one.

Does exactly what is described.

Just as described, packaged well and met expectations

I have 2 of these on my small RV type solar array and 2 DCM 110AH batteries one on each battery - hooked to a 2000W operating inverter. Tried to run a 1 HP air compressor on it . If the compressor tank was at zero to start, and the motor warm, the start surge on the motor was just below the 4000W peak that the inverter can do momentarily - but with a restart on it, it pulls hard enough that it tripped 1 and then both as it pulled over the 100A input limit. Turns out on surge, I was trying to pull nearly 400A through them (and way more than the 4000W output). I knew, I tried, and it tripped the breakers. I had an amp clamp type meter on the 12v circuit and they each tripped right at setting. Made me very happy to know that they worked correctly.

Nuts stripped very ez on 1 of the 3/ somethings are operating error, but low quality doesn’t help
