Bussmann 80M-1-1/3 – Frequently Asked Questions

1) Will the Bussmann 80M-1-1/3 fuse work on a 48V DC telecom power plant?
Yes. The 80M-1-1/3 is rated 160 Vdc, so it covers the common DC bus voltages used in telecom equipment, including 48V plants, as long as your circuit voltage stays at or below 160 Vdc. It is a DC rating, not an AC rating, and the fuse is built specifically for telecommunication circuit protection.
2) What size fuse holder does the Bussmann 80M-1-1/3 fit?
It is a cylindrical fuse body measuring .28 x .28 x 2.685 inches, so it drops into standard cylindrical telecom fuse holders and panel clips sized for that diameter and length. Check the clip spacing or holder bore against those numbers before ordering a tray of them.
3) Is 1.33A an odd rating, and can I substitute a 1A or 1.5A fuse instead?
1.33A is a deliberate rating in the Bussmann 80M telecom series, chosen for low-current DC branch circuits where a 1A fuse would nuisance-open and a 1.5A would let too much through. Substituting either changes the protection point on that circuit, so match the 1.33A rating unless the equipment maker specifies otherwise. The 80M-1-1/3 is the part number that carries this rating.
4) How do techs tell the 80M-1-1/3 apart from other amp ratings in the same fuse panel?
By colour. This one carries a white colour code on the body, which is how the 80M series marks rating so a technician can spot the right value in a crowded telecom panel without pulling the fuse and reading the stamp. Useful if you are stocking several amperages side by side in a central office.
5) Does the Bussmann 80M-1-1/3 have a blown-fuse indicator pin?
No. It is a non-indicating design, so there is no pop-out pin or flag to show it has opened. You verify it with a meter or by the alarm on the fuse panel. If your maintenance routine depends on visual blown-fuse indication at the panel, you want an indicating version of the fuse instead.
6) Is the 80M-1-1/3 suitable for AC branch circuit protection in a building panel?
No. This is a DC-rated telecom fuse at 160 Vdc, built for equipment-level protection in central office and network gear. It is not a branch circuit fuse for a building distribution panel. For AC feeder or branch protection use a fuse carrying an AC voltage rating and class designation appropriate to that panel.
7) How does the Bussmann 80M-1-1/3 ship for stocking spares?
It comes in standard packaging, which is the usual format for keeping a shelf of telecom fuse spares in a central office or MRO crib. Listed weight is .5 lb. Stock it against the amperage you need, since the 80M series splits by rating and each value carries its own colour code.
