Automotive fuses

Some time ago I posted about interesting looking fuse holder I was considering to an application. At the time I found out that these aren't really rated for high voltage applications.

Now I was browsing fuses again and this little thing turned up:

Whoah, that actually looks like something I could use.

Except that those small automotive fuses aren't really rated beyond 80V DC (and typically no AC rating at all). So what good is holder with 250v rating (both AC and DC) when you can't get similarly rated fuses easily?

So I'm still looking...
