<div dir="auto"><div>A fuse with a higher voltage than the line voltage is fine. Given that, the amperage is the critical part, and maybe fast/slow blow depending on your application.<br><br></div><div dir="auto">If you intend to use it with a switching supply that accepts 120-240VAC (which are becoming more common) it should have a 250V fuse in the case that it is ever run from the higher voltage.
