Bussmann 1-1NBUNA3-15 – Frequently Asked Questions

1) What voltage and amp rating does the Bussmann 1-1NBUNA3-15 fuse carry?
The Bussmann 1-1NBUNA3-15 is rated 3.15A at 1.1 kV. That voltage class puts it in medium-voltage control and distribution service, not standard 250V or 600V branch circuits, so don't drop it in as a substitute for a common low-voltage industrial fuse just because the amp rating matches.
2) Is the 1-1NBUNA3-15 a clip-in fuse or does it bolt into the holder?
It's a bolt-on fuse. The terminals bolt down rather than press into spring clips, which gives a lower-resistance joint that stays tight under vibration. If your existing holder is a clip or ferrule style, this fuse won't seat in it, you need bolt-pad provisions.
3) Does this Bussmann fuse have a blown-fuse indicator or striker pin?
No. The 1-1NBUNA3-15 is a non-indicating fuse, so there is no pop-out pin or visual flag to show it has operated, and nothing to trip a microswitch or indicator circuit. Crews troubleshooting a panel will need to meter across it or pull it to confirm. If your panel design relies on a striker to actuate an alarm or a trip mechanism, specify an indicating fuse instead.
4) What is the manufacturer part number for this Bussmann bolt-on fuse, and how is it packaged?
Order it as Bussmann MPN 1-1NBUNA3-15. It ships in standard packaging, so it is handled as an individual catalog item rather than a bulk-pack or strip assortment.
