Bussmann FMS-20 – Frequently Asked Questions

1) Will the Bussmann FMS-20 plug into a standard maxi fuse block?
The FMS-20 is built to the slotted micro female maxi footprint, so it drops straight into maxi-style fuse blocks and holders that take that terminal pattern. It's a direct plug-in replacement, no adapter, no rewiring. If the holder in the vehicle takes a standard blade or mini blade fuse rather than a maxi, this is the wrong body style and won't seat.
2) What amperage is the Bussmann FMS-20 automotive fuse, and what does the blue color mean?
Rated 20A. The LT Blue housing is the color code that goes with the 20A rating, which is what lets a tech pull a panel cover and read the circuit rating without pulling every fuse. Match the rating on the fuse you removed; putting a higher-amp fuse in a circuit sized for 20A defeats the protection.
3) What is the Bussmann part number for a 20A slotted micro female maxi fuse?
FMS-20 is the Bussmann manufacturer part number. FMS is the slotted micro female maxi series and the 20 is the amp rating, so the series numbering runs by amperage across the family. That's the number to quote when ordering or cross-referencing against a vehicle fuse chart.
4) Is the Bussmann FMS-20 fuse RoHS compliant for fleet and municipal purchasing specs?
RoHS Compliant, stated on the product record. For fleet, municipal, and institutional buyers who have to document restricted-substance compliance on consumable electrical parts, that's the compliance claim carried on the FMS-20.
5) Can I use a slotted micro female maxi fuse like the FMS-20 in a building electrical panel?
No. The FMS-20 is an automotive fuse for 12V and 24V vehicle circuits in cars, trucks, and commercial fleet equipment. It is not a branch circuit or panel fuse and has no place in building power distribution. For a facility panel you need a listed power distribution fuse in the correct class, not an automotive blade-type.
