3 Pack 300A Circuit Breaker with Manual Reset Fuse Holder for Car Audio Marine Boat Stereo Switch, with Wire Lugs Copper Washer

These inline circut breakers work. Easy to install and is worth the money.

Work good so far. Hooked one up to two electric fans on my 85 4runner.

Excellent product

A previous purchase suddenly failed. No obvious reason. Replacement price allowed an easy replacement. I do like the product but question reliability in light of the failure of one of two I was using.

Arrived on time and is exactly what I ordered. I buy Circuit Breaker Fuse and Mega Fuse for my electrical protection. I use Circuit Breakers for branch circuits off the main battery. These branches could be for Audio, EFI computers and even the main electrical connection to the car fuse panel. I've even use these breakers to shut off the car when I leave the car a car show so no one can steal it. I've been very happy with them. The only Con I have is these breakers are not good it high temp locations so keep them away for your exhaust or headers. I had one fail when I mounted it just above my headers even though my hearders were wrapped to reduce heat. Good product overall. Must have and good buy

Works great for making your our wiring system and has a good price

I bought a 3 pack of the 50 amp breakers and 2 of them no longer work. They were used on the 12v DC battery line on my camper. I got them because they stated they could be used on a camper/RV or marine applications, and it's printed on them that they are WATERPROOF. They worked great for a little while until they got wet from the rain, then one of them failed completely, tripped the breaker and wouldn't reset no matter what I did. Completely disconnected the cables and it still won't reset. The other one I had was still working, BUT was only letting 10V through to the camper. I had to bypass the breaker so I could use my camper until I could get a better replacement for it.
