⚡ Discover the Reliable 420844 1 Resettable Circuit Breaker without Limitations Review

I used this on my Thomas skid steer loader. The old man had a broken body and kept tripping. Very frustrating. It took a while to narrow down the problem. I installed it 4 months ago and haven't had any problems since. Least expensive repair to date on this car

Works as it should. Replaces a similar 40 amp CB which has become unusable after almost 4 years of life in the hold of a sea water boat. If this lasts that long, I'll be happy. Case purchased separately unused. I found it pretty well useless in my case.

These are quality circuit breakers. Not like the cheap ones from the auto parts store. I have two of these as overcurrent protection for 12v electric radiator fans. I recommend purchasing covers (Sea Dog 420840-1) if you plan to mount them under the hood or in a location that will be exposed to moisture. Rubber coatings prevent the posts from corroding over time.
