DaierTek 50 Amp Circuit Breaker, Waterproof Marine Circuit Breaker 12V 24V 48V Resettable Inline Fuse Switch, 12 Volt 50A Breaker for Boat Trolling Motor Car Automotive -2Pack

Easy to use

Great for my application.

Bought two 60amp breakers for a project. After installing both in the project, there was a sporadic and repetitive fault. Doubting my abilities, I used new cables and added an extra ground. The oddest symptom was a drop in voltage across one of the breakers. When i removed that breaker the problem was solved. So i believe one out of two were bad.

I haven’t any issues. They worked as advertised !

Nice for easy disconnecting

Installed in my camper after doing a lithium upgrade. Overall works very well however in high current situations (brewing the morning coffee in a 750 watt single serve drip pot, and watching the morning news on TV and charging the laptop) where the load is sustained above around 65 amp for a few minutes the breaker will trip and will not reset until it cools down. Thankfully it hasn't happened often because rarely do we do all of that at one time. I suspect this is a thermal issue and will likely have to upgrade to a higher rated breaker.

works great

Or it's really sensitive/fast. I have these on the cables to my solar battery pack, first sunny day after install, one of them tripped, while charging at about 50 amps (my breakers are 100A version).I bypassed it, and an hour later the other tripped.Both of these "100A" breakers tripped, when an in-line 63 amp CHTAIXI breaker did not.MPPT charging without a load shouldn't involve spikes or surges, so I conclude that hese don't provide indicated current capacity.
