TIYANG 60 Amp Circuit Breaker 12V - 72V Manual Reset Circuit Breakers for Boat Solar Automotive RV Truck

I needed a replacement for a similar red--buttoned and -levered 100 Amp device, as it kept blowing when I started my warm vehicle engine. The application is as a battery disconnect switch for my RV's engine, using the negative terminal of the battery. This unit worked fine, after repeated engine start-ups. When cold, a 100-amp unit does fine, but when the engine is warm, sometimes the starter is a little wonky, and takes a few seconds to get up to speed. The 100 amp unit I had was prone to blowing, even using it on the negative battery terminal. Very frustrating when you are gassing up at Costco, with people in line behind you! Recommend this unit. It would be nice if I could find a similar unit with 3/8 inch lugs rated at 300 amps, though, just for safety's sake. Don't buy ANY battery disconnect for ANY vehicle unless it has 3/8-inch lugs. Many have 1/4-inch lugs, and you will be wasting your money. So far, so good. If I have any problems, I will report back.

Only had about 100 amps running thru this breaker. It failed and killed my $300 battery and almost ruined my alternator. Do not buy. Try a real brand. Use at your own risk. I would not use in a wet environment even though it says waterproof. These are junk.

Great Price and works perfect for 24v. Minn Kota.

I used this to replace a 200amp switch that had smaller studs. This one has 3/8 studs. The one I got first wouldn't run my travel trailer microwave for more than 2min. This one works great.

Had these on the boat for a couple months and they started showing signs of corrosion.Apparently no warranty.
