看了一下你的問題，Google是這樣解釋的

You can never apply a fuse whose max voltage rating is smaller than the application voltage. You can replace a 125V fuse with a 250V fuse of equal amperage as long as the application voltage is 250V or less. You cannot replace a 250V fuse with a 125V fuse of equal amperage if the application voltage exceeds the 125V.
