Bussmann KRP-C-1350SP – Frequently Asked Questions

1) Can I use a 1350 amp KRP-C fuse on a 480V or 600V service?
Rated 600 Vac and 300 Vdc, so it covers 480 V and 600 V three-phase service as well as lower AC systems. On DC it is limited to 300 V. Interrupting rating is 300 kAIC at 600 Vac.
2) Will this fuse hold up to motor inrush without nuisance blowing?
It is a time-delay current-limiting fuse, rated 4 seconds at 500% of rating. That means it will carry roughly 6750 A for about 4 seconds before opening, which is what lets it ride through motor starting and transformer inrush while still clearing a fault fast.
3) Is 300 kAIC enough for my service entrance available fault current?
The 300 kAIC at 600 Vac interrupting rating on this 1350 A Class L fuse exceeds the available fault current on virtually any 600 V or lower service, and because it is current-limiting it also cuts the let-through energy reaching downstream gear. Compare the figure against the available fault current stated on your coordination study.
4) Does the KRP-C-1350SP have a blown fuse indicator?
No. It is non-indicating, so there is no visual flag or pop-up pin to show it has opened. Troubleshooting means metering across the fuse or checking continuity with the circuit isolated. If your maintenance crew relies on a visual check, plan for that.
5) Should I use a Class L fuse like this or a Class J or RK1 for my main?
Class L is the class used above 600 A, and this one is a 1350 A device. Class J and Class RK1 fuses top out at 600 A, so they are not an option at this rating. For a 1350 A main switch or bolted pressure switch at 600 V or below, Class L with bolted blade ends is the correct form factor; the smaller classes only come into play on downstream feeders.
6) How heavy is a 1350 amp Class L fuse, and is it a one-man change out?
About 5.72 lb each. That is manageable by hand, but on a large switch you are working overhead in a bolted connection, so budget for torquing the blade bolts to the switch manufacturer's spec and for the space the 10.75 inch body needs.
7) Is the Bussmann KRP-C-1350SP a genuine Eaton part and does it carry CE marking?
Yes, it is the genuine Eaton Bussmann series part, ordered by the number KRP-C-1350SP, and it is CE Marked. Ships in standard packaging.
