In the line voltage (120v and up) world, fuses are made by Mersen, Littelfuse, and Bussman. Mersen owned Ferraz and Gould-Shawmut and sold fuses as Ferraz-Shawmut until a few years ago when they rebranded to Mersen. Bussman is owned by Eaton, and Littelfuse is an independent company.

Those are the only three manufacturers I ever see specified by electrical engineers in construction specs.
