Bussmann KTS-R-175 – Frequently Asked Questions

1) Can I use a Class RK1 fuse like the KTS-R-175 in a panel that currently has RK5 fuses?
Yes. Class RK1 and RK5 share the same Class R dimensions and rejection feature, so a KTS-R-175 will physically fit any 175 A, 600 V Class R holder that currently holds an RK5. The difference is let-through: RK1 clears with lower peak current and energy than RK5, which generally improves downstream component protection. Going the other direction, RK5 into equipment specified for RK1, is not an equivalent substitution.
2) Is the KTS-R-175 a fast-acting fuse or a time-delay fuse for motor loads?
It is fast-acting, part of the Bussmann LIMITRON KTS-R line, with a single element. Fast-acting means no intentional time delay, so it will not ride through motor inrush the way a dual-element time-delay Class RK1 will. Use it on non-motor loads such as panelboard mains and feeders, switchboards, and circuits feeding electronic or resistive loads. For across-the-line motor starting, specify a time-delay Class RK1 instead.
3) Can I tell by looking whether a KTS-R-175 has blown?
No. The KTS-R-175 is non-indicating, so there is no pop-out pin or window to show an opened element. Check it with a meter across the blades, or specify an indicating fuse or a separate blown-fuse indicator if crews need a visual check on a panelboard.
4) Can I use a 600 volt fuse like the KTS-R-175 on a 480 volt or 240 volt circuit?
Yes. A fuse voltage rating is a maximum, so the 600 V KTS-R-175 can be applied on any ac system at or below 600 V, including 480Y/277 and 208/240. You cannot go the other way and put a 250 V fuse in a 600 V circuit. Make sure the holder itself is rated 600 V.
5) How do I order the exact Bussmann 175 amp LIMITRON fuse for a panelboard replacement?
Order by the Bussmann part number KTS-R-175, which is the 175 A, 600 V Class RK1 fast-acting LIMITRON in standard packaging. Fuses are sold individually, so for a three-phase panelboard main you will need three. The part is CE marked.
6) What is the KTS-R-175 body made of and how much does it weigh?
The tube is melamine glass with 70/30 brass end caps, weighing 1.23 lb. The melamine glass body handles the thermal and mechanical stress of a 200 kA interruption without rupturing, and the brass caps carry 175 A continuously in bolted or clip connections.
