Bussmann KRP-C-601SP – Frequently Asked Questions

1) Can I use the KRP-C-601SP on a 480 V three-phase service?
Yes. It's rated 600 Vac, so it covers 208, 240, 480, and 600 V AC systems. DC rating is 300 Vdc, so don't apply it above that on a DC bus.
2) Will this fuse hold in on motor and transformer inrush?
It's a time-delay, current-limiting fuse with a 4 second minimum opening time at 500% of rating, so it rides through transformer magnetizing inrush and motor starting current instead of nuisance-opening. That time delay is why KRP-C is the usual choice for service mains, feeders, and large motor circuits.
3) Does the KRP-C-601SP have enough interrupting capacity for a high-fault service entrance?
Interrupt rating is 100 kA at 300 kAIC Vdc, per the published rating. As a current-limiting fuse it also cuts the let-through energy, which is what lets downstream gear be series-rated on a high available-fault service.
4) Why is the fuse rated 601 A instead of 600 A?
Class L fuses start at 601 A, which is where the class picks up above Class J and Class RK's 600 A ceiling. The KRP-C-601SP is the smallest rating in the KRP-C line, so a 600 A main protected by a Class L switch uses this fuse rather than a 600 A cartridge.
5) Is there a blown-fuse indicator on this one?
No. The KRP-C-601SP is non-indicating, so there's no pop-up pin or light to show it has opened. Maintenance crews need to check continuity or voltage across the fuse to confirm, which matters if you're standardizing on visual indication across a switchboard.
6) How much does a 601 A Class L fuse weigh, and is it a one-person change-out?
3.8 lb per fuse, 8.63 inches long and 2.53 inches across the body. Light enough to handle solo, but both ends bolt down, so plan on a wrench and clearance behind the switch to reach the mounting bolts rather than a clip-in pull.
7) Is the Bussmann KRP-C-601SP RoHS compliant for a spec submittal?
Yes, RoHS compliant. Order it by the genuine Bussmann part number KRP-C-601SP so the submittal matches the fuse in the switch.
8) How many do I need for a three-phase main switch?
Three, one per phase, and they should all be the same rating and type. The KRP-C-601SP is sold in standard packaging as a single fuse, so quantity three covers a three-pole switch. Buying a spare set at the same time is common practice on service mains.
