12V 24V 50A Automatic Reset Circuit Breaker with Stud Bolt and Cover for Car Automotive RV Boat Trolling Motors Solar Battery Chargers DC System, 2 Pack

My travel trailer had about 5 current limiter (circuit breakers) just like this. But... the master breaker that went from the trailer circuit system (13.7 volts) to the batteries on the 'tongue' of the trailer, FAILED to pass the current to the batteries when they got really low!Although the breakers were for 50 amps, apparently the low batteries in conjunction with the trailer converter box, were sucking MORE than 50 amps to keep charged up? I dunno, but... the existing breaker was shutting down, allowing zero flow to the batteries!So... i bought these... Two of them here are about as cheap as only ONE of them from other sellers here on Amazon. So, I bought this 2-pack. Great! Now I have an excellent replacement (same size, same shape, exact same mounting holes, exact same red rubber cover, same size terminal bolts and nuts), and... I have a spare for the same price as ONE from other sellers!I tested these two .... set them up with 14 volts, and ran the current up.... at exactly 49 amps, each of them 'popped' and stopped all current flow. Then... it took just about 20 seconds to cool off, and they both reset and allowed current to flow, once again. Just as advertised, these two did the job and the one I used mounted perfectly on the trailer frame just as the other one that got replaced.In my case, they worked great. You might use them in other situations, installations... any where you might need 50 amp current limiter, that is SELF (automatic) re-setting, once the current flow subsides below 50 amps. It works on heat. More than 50 amps heats up the bi-metal internal contacts, and it will pop. After it cools, it sets, no action from you required!

I had lost the ability to charge the coach batteries on my motorhome. I tried everything I could think of to remedy the situation. Nothing worked. I discovered one of these little in-line fuses and decided to try exchanging it for a new one. The old one was a manual reset fuse that gave the impression it had been reset when pushing the reset button. The exchange was super easy, five minutes maximum. After the install, magic, the battery started charging as it should. If you're having electrical issues on a vehicle, look for one of these in-line fuses and change it out. These fuses are self resetting and come with a nice cover.

we were having issues with things not running on battery power. the awning and slide usually goes on 12V. but they stopped working. someone suggested replacing these things. as they are exposed to weather and elements and can go bad. we did. and sure as pie, problem fixed!! they are the little junctions that connect battery power to everything else and they usuall sit outside in front near the batteries

Used two a 30a and a 50a to replaced older ones on RV. Seems like good quality, only time will tell. Same location for screw holes as old ones, so that was good for easy installation. Would buy again.

5 minute replacement, fit right in my original 50amp space. tested perfect.

Great product at a great price.

My slide out motor kept cutting out, after some ccx research I found this was my problem. I put these in and it's all good now. Worked perfectly.

Great look, Easy to install. The problem I have is once you install the vable is warps the silicon and it is hard to get closed. Once you get it closed, I find that is is open every other day or so. I have tried multiple ways of installing these and nothing seems to work. They are excellent if you dont care to much about the waterproof part. I would not buy these again. I would try a different brand.

Good quality.

Semble être de bonne qualité 👍🏾🧐

They look great. Price is good . Thank you
