Review on 🔌 High-Quality 12V/24V 10A Automatic Reset Circuit Breaker with Cover - Ideal for Battery Chargers, Trucks, Buses, Electric Cars, and Car Engines by Peter Sullivan

They operate normally but do NOT have automatic reset; Instead, they are manual resets. In the pictures you can see a black reset button. When these travel, they pop up. After a minute or two you can put it back in and the chain will start working again. I bought them to replace a 30A short circuit breaker in my RV (1995 RoadTrek Popular 190) - to protect the converter/charger from high currents (because the alternator is delivering over 30A to the battery) . The breaker part works as expected. After a minute or two, at about 33 amps, the switch on the charger trips; It starts up fairly quickly when the alternator gets close to 40 amps. But to my dismay, it doesn't auto-reset as expected and it was installed in a hard-to-reach location. But if the manual reset works for you, you should be able to use them as expected. If they change their description to "manual reset" I would give it a 5 star rating.
