"商品説明では、DC12-24V用で、動作電圧DC6V~28Vとなっているが、商品には「125/250Vac 50Vdc 50/60Hz」と表示されている。交流と直流の表示があることや、そもそも電圧や周波数って何か関係あるの?と思い念のため12Vで規定以上の負荷をかけてみたが全く動作しなかった。"

Use these on my travel trailer to replace the original circuit breaker. I like that they have the rubber cap to keep the wire connection from being exposed to road corrosion.

I took the wife camping for Valentines weekend, and when we got to the campgrounds our trailer failed to function properly (electric tongue jack, electric stabilizers, and slide outs refused to work). I did not have my multimeter or tools with me as it was a spur of the moment trip, so we had to head home. Once home I discovered one of the two units on the trailer was bad. Replaced them both with these and everything functioned like normal again. A pair of these will forever be in my, now, dedicated repair kit that stays in my trailer at all times! The quality is very good and they mounted up to the preexisting holes perfectly.

Works perfectly, and my lawnmower has not skipped a beat since I installed one of these. Although it comes in a 2 pack, I'm guessing I won't ever have to even use the second one. And, BTW, the cost of 2 of these was much cheaper than a single component at my local brick and mortar.
