I don't know if this is what you're looking for, but Bussman has a product on their website called the "Vehicle Electrical Center" which appears to be a protected fuse panel. You can check it out at:
www.bussauto.com
Check under "Products" and then it should be the top choice in the list. From their description, the panel has a cover over the fuses and can handle up to 200 amps of current. Perhaps this will help?
