Bussmann CHM1DI-48U – Frequently Asked Questions

1) What size fuse does the Bussmann CHM1DI-48U fuse holder take?
The CHM1DI-48U accepts 10 mm x 38 mm cylindrical fuses. That is the only fuse size it's built for, so a 14x51 or a 22x58 body will not seat in it. If your panel drawing calls out a class CC or midget-style 10x38 link, this is the holder that matches.
2) I need three-phase or multi-pole protection. Is one CHM1DI-48U enough?
One CHM1DI-48U protects a single pole only. For a two- or three-pole circuit you order one module per pole and gang them together on the rail. The modular format is built for exactly that, which is why the depth per module is only .69 in.
3) Will this Bussmann fuse holder hold up inside a hot equipment enclosure or an outdoor solar combiner?
Operating range is -20 C to 90 C. The 90 C top end covers most sealed control cabinets and inverter enclosures that run warm. The -20 C floor is the one to watch on unheated outdoor installs in cold climates, since anything below that is outside the rating.
4) What exactly is the part number I should order for the Bussmann CHM 48 Vdc single-pole holder?
The manufacturer part number is CHM1DI-48U, from Eaton's Bussmann series CHM modular fuse holder family. The 48U in the designation tracks the 48 Vdc UL rating, and the 1 is the single-pole count, so adjacent CHM models with different digits are different voltage or pole configurations.
