Bussmann KRP-C-3200SP – Frequently Asked Questions

1) Will a Bussmann KRP-C-3200SP fit a standard Class L fuse holder?
The KRP-C-3200SP is a Class L fuse rated 3200 A at 600 V, so it lands in Class L bolt-in mountings sized for that amp rating. Overall size is 10.75 x 5.03 x 5.03 inches, and it weighs 22.15 lb, so plan on bolt-on blade terminals and a switchboard or bolted pressure switch built for that footprint rather than a clip-style holder.
2) Is the KRP-C-3200SP rated for a 480V service, or only 600V?
It is a 600 V fuse, which covers 480 V and 208 V systems as well. Use it at or below 600 Vac only. Interrupting rating is 300 kAIC at 600 Vac, which is what you need on a large service where available fault current is high.
3) Will this 3200 amp fuse hold on motor inrush without nuisance blowing?
It is a time-delay, current-limiting fuse with a 4 second minimum opening time at 500% of rating, so it rides through motor starting and transformer inrush instead of clearing on it. That is why it is used ahead of large machinery disconnects and distribution switchboards rather than a fast-acting fuse.
4) What is the correct replacement part number for a 3200 amp Class L Bussmann fuse in a switchboard?
Order Bussmann KRP-C-3200SP. That is the genuine Eaton Bussmann manufacturer part number for the 3200 A, 600 V, Class L time-delay fuse in the KRP-C (Low-Peak) series. Matching the exact catalog number matters because Class L fuses of the same amp rating differ in time-delay characteristic, and mixing types changes your selective coordination.
5) Does the Bussmann KRP-C-3200SP have a blown-fuse indicator?
No. It is a non-indicating fuse, so there is no visual pop-out or flag to show it has opened. On a service this size, crews verify with a meter across the fuse or by checking voltage downstream. If your maintenance procedure depends on a visual check, you will need an external indicating means at the switch.
6) Is a 300 kAIC fuse enough for a high fault current service?
300 kAIC at 600 Vac is the top of the range for 600 V overcurrent protection, and because the fuse is current-limiting it also cuts the let-through energy reaching downstream gear. That combination is what lets you series-rate or protect equipment on a service where calculated available fault current runs into the six figures.
7) How heavy is a 3200 amp Class L fuse, and is it a one-person change out?
Each fuse weighs 22.15 lb and measures 10.75 inches long by 5.03 by 5.03. At that weight and length, plan the change-out as a two-hand lift in a de-energized switchboard, with room to line up the bolt holes on both ends. Shipping is standard packaging, one fuse.
