12V 24V Auto Reset Circuit Breaker 50A for Automotive Solar Boat RV and More, Type 1 DC Trollig Motor Resettable Breakers 50 Amp 12 Volt- 28V DC with Cover Stud Bolt, 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!

Worked well good replacement

The media could not be loaded. Added this to my 12 volt RV fridge, works great!!

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

As described

The original breaker lasted 10 years out in the elements so it was a no brainer which one to buy.

Bought this to replace my old ones on my camper for my 12volt system i like that they have a cover over the lugs to protect them from grounding out if rubbing up against something they shouldn't but you can mount them with screws if need to be which i recommend Also these will Reset AUTOMAICLLY if to much Amprege is supplied you just have too wait for them to reset. if they trip over and over again then there is a issue with the electrical system and you need to look else where for the problem.

Works ok but not very waterproof. Starting to corrode from water exposure already...
