Bussmann GLR-8 – Frequently Asked Questions

1) What amp rating is the Bussmann GLR-8 fuse?
The GLR-8 is the 8 amp version of the Bussmann GLR series. In this series the number following GLR is the ampere rating, so GLR-8 opens at 8 amps. Voltage rating is 300V, and the element is fast-acting. Ordering is by the 100 piece pack.
2) How many fuses come in a pack of the Bussmann GLR-8?
One hundred fuses per pack. The GLR-8 is sold as a 100 count pack, not as a single fuse, so it suits an MRO crib or a service van stocking a common amperage rather than a one-off replacement.
3) Can I use a 300V GLR-8 fuse on a 120V or 240V control circuit?
Yes. A fuse's voltage rating is a maximum, so the 300V rated GLR-8 can be applied at any circuit voltage up to 300V, including 120V and 240V control circuits. What you cannot do is go the other way and use it above 300V.
4) Will the GLR-8 fit my existing fuse holder or fuse block?
The GLR-8 is a small-dimension fuse and drops into compatible small-dimension holders and blocks, which is how it is normally used as a replacement in Eaton Bussmann series holders. Match it to the holder your panel already uses and confirm the holder is rated for at least 300V and 8 amps before swapping.
5) Should I use a fast-acting GLR fuse or a time-delay fuse for my equipment?
Fast-acting is the right choice where the load has little or no inrush and the components are sensitive: electronic boards, instrumentation, control circuits, panel metering. The GLR element opens quickly on fault current so the downstream parts see less energy. If you are protecting something with a start-up surge, a small motor, a transformer primary, or a solenoid-heavy circuit, a fast-acting fuse will nuisance-open and you want a time-delay small-dimension fuse instead.
6) Can I standardize a facility's control panels on the Bussmann GLR series?
That is a common use for it. Buying the GLR-8 in 100 piece packs lets a plant or building maintenance group carry one amperage across control panels and electronic equipment, and because it is a genuine Eaton Bussmann series part it matches the holders already installed in most of those panels. You would stock additional GLR amperages alongside it for circuits fused at other values.
7) Where do I find the full electrical data for the Bussmann GLR-8?
Eaton publishes a spec sheet for the GLR series, and it is linked from the product data for the GLR-8. That document carries the series interrupting rating and time-current data if you need it for a coordination study.
