I was looking for a general-purpose breaker for DC. When you are in trouble with fixing, there is no handling with Mr. Mon Tarou, but since the thing called "Eubon 's BH mounting plate is cheap, I think that it is easy to use when used in a set.
Although it is not as good as a camper, it will be installed safely in the sub battery for power supply as it improves the night in the car. I decided on this because I read the specifications of the manufacturer and it was DC compliant and the price was cheap. Because the size was bigger than I thought (it is the size of a normal breaker ...) I use it as a main power supply and I think whether to use a fuse for a small capacity circuit after distribution.
