Bussmann LPN-RK-80SPI – Frequently Asked Questions
1) What amp and voltage rating is the Bussmann LPN-RK-80SPI fuse?
The LPN-RK-80SPI is an 80 amp fuse rated 250 Vac and 250 Vdc. Because the rating is 250 V, it can be applied on 240 V and 120/240 V circuits, but not on a 480 V system.
2) Is this fuse OK for a motor circuit that draws high inrush on start?
Yes. It is a dual-element time delay fuse, so it rides through the brief inrush of a motor or transformer while still opening on a sustained overload. That is the reason dual-element Class RK1 fuses are specified for motor branch circuits instead of fast-acting types.
3) What short-circuit interrupting rating does the LPN-RK-80SPI have?
100 kAIC at 250 Vdc. That is what lets it be used as the overcurrent device establishing a high short-circuit current rating on equipment fed from a stiff service.
4) Can I use this fuse on a DC circuit?
Yes, the LPN-RK-80SPI carries a 250 Vdc rating alongside its 250 Vac rating, with a 100 kAIC interrupting rating at 250 Vdc. Keep DC applications at or below 250 volts.
5) How many fuses come in a pack of Bussmann LPN-RK-80SPI?
Quantity is 5 per pack in standard packaging. For a three-phase disconnect that uses three fuses, one pack covers the set plus two spares for the shelf.
6) Is the LPN-RK-80SPI current-limiting, and does that matter for my panel?
Yes. Class RK1 fuses are current-limiting, so they cut the let-through energy during a fault. That is what allows downstream equipment and conductors to be protected against the available fault current rather than simply disconnected after the fact.
7) Does this Bussmann fuse have an insulated end cap?
It has an electrically isolated end cap, which reduces the chance of an accidental phase-to-ground or phase-to-phase contact when pulling or seating the fuse in a crowded disconnect.
8) Is this Bussmann fuse marked for European compliance?
The LPN-RK-80SPI is CE Marked, which matters if the panel or machine it goes into is being built for export or to a European customer's documentation requirements.
