Review on Premium High-Current Circuit Breaker, Allkpoper 30A-300A Amp Breaker with Manual Reset Switch and Fuse, Waterproof for Boat Marine RV Yacht Battery Trailer Bus Truck, 12-48V DC (30A) by Sam Davenport

This unit has been working for about a week. I could set and reset it as a toggle while working on my project. Then the project experienced its first failure. It was not clear that the block had worked. I tripped and flipped the switch and nothing happened. I assumed my components were damaged and bought new ones. After reassembling I reset the switch again and still nothing happened. Looks like the switch is broken, not my other components. The breaker is damaged and makes contact immediately when I shake the red flip-up wiper. Bad design cost me quite a bit of money to buy new parts that were actually fine. I went to the switch and fuse. Don't waste your money on it.
