Bussmann GMA-315-R – Frequently Asked Questions

1) What amp ratings does the Bussmann GMA-R fast-acting fuse come in?
Three ratings are offered in the GMA-R series: 3.15 A (GMA-315-R), 6 A (GMA-6-R) and 7 A (GMA-7-R). Match the amperage called out on the equipment label or the old fuse body exactly, since a fuse is sized to the circuit it protects, not chosen up or down for convenience.
2) Will a Bussmann GMA fuse fit a standard fuse clip holder?
The GMA fuse is a ferrule end by ferrule end cartridge fuse, so it drops into clip style or cartridge holders that grip the metal end caps. It is not a bolt-in or blade type fuse, and there are no screw terminals or tabs on it.
3) How fast does the Bussmann GMA-R fuse clear an overload?
It is a fast-acting fuse rated to open within 2 minutes maximum at 200 percent of rated current. That short time-current characteristic is what makes it suited to electronics and control circuits with little inrush. If your load is a motor, transformer or anything with a heavy starting surge, a fast-acting fuse like this will nuisance-blow and you want a time-delay type instead.
4) My equipment manual calls for a GMA-7-R. Can I substitute a different Bussmann fuse?
When an OEM specifies GMA-7-R, order that exact part. The GMA-R family is a model-specific replacement line, and the designation carries the amperage and the fast-acting characteristic together. Dropping in a different series changes the time-current response even if the amp rating matches, which is how sensitive boards get damaged on the next fault.
5) Does the GMA fuse have a blown-fuse indicator?
No. The GMA-R is a non-indicating fuse, so there is no pop-out pin or visual flag on the body to show it has opened. Troubleshooting means pulling it and checking continuity, or reading voltage across the holder. If your maintenance crew needs to spot a blown fuse without pulling it, specify an indicating type.
6) Is the Bussmann GMA a small dimension fuse like a 5x20mm glass fuse?
The GMA-R is catalogued as a small dimension cartridge fuse with ferrule ends, the class of fuse used inside equipment and on PCB-mounted or panel clip holders rather than in branch circuit disconnects. Order by the GMA part number your equipment calls out so the body length and diameter match the holder you already have.
7) Do GMA-R fuses come in bulk packs for MRO stock?
Packaging is standard pack for the GMA-R fuses, with amperage as the only option to choose (3.15, 6 or 7 amp). For facilities that stock spares, keeping each of the three ratings on the shelf covers any GMA-R callout you run into without reordering mid-repair.
