Bussmann KTS-R-6 – Frequently Asked Questions

1) Will a Bussmann KTS-R-6 fit a Class R fuse block with the rejection feature?
Yes. The KTS-R-6 is a Class RK1 fuse with ferrule end x ferrule end terminations, so it drops into Class R rejection clips as well as standard ferrule clips of the same size. The body measures 0.8 x 0.8 x 5 inches, which is the 600 V ferrule case size for this amp range.
2) Can I use a KTS-R-6 to replace a 6 amp Class H or Class K5 fuse in a 600 V panelboard?
Physically, a Class RK1 ferrule fuse will seat in standard non-rejection clips, so a 6 A, 600 V Class H or K5 fuse of the same case size can be replaced by the KTS-R-6 and you gain a 200 kAIC interrupting rating at 600 Vac instead of the much lower rating those older classes carry. The reverse is not true: once a holder has Class R rejection clips, a non-rejection fuse will not fit.
3) Is the Bussmann KTS-R-6 a fast-acting or time-delay fuse, and can I use it on a motor circuit?
It's a fast-acting LIMITRON fuse with a single element, no intentional time delay. That makes it suited to protecting circuits without large inrush, such as panelboard feeders and non-inductive loads. A motor circuit that draws locked-rotor inrush will nuisance-open a fast-acting fuse at 6 A; for motors you want a dual-element time-delay Class RK1 fuse instead.
4) Can I use a 600 V fuse like the KTS-R-6 on a 240 V or 480 V circuit?
Yes. The KTS-R-6 is rated 600 V, and a fuse may be applied at or below its voltage rating, so 120, 240 and 480 V circuits are all fine. You cannot go the other way and put a 250 V fuse in a 600 V circuit.
5) Does the KTS-R-6 have a blown-fuse indicator?
No. It is non-indicating, so there is no window or pop-up pin to show it has opened. If you maintain a facility and want visual confirmation at the panel, you'll need to meter the fuse or specify an indicating type; otherwise plan on continuity testing during troubleshooting.
6) What exact part do I order to standardize 6 amp 600 V Class RK1 fuses across a building?
Order Bussmann part number KTS-R-6. It ships in standard packaging and is CE marked. Because it is a single catalog number covering 6 A at 600 V in the Class RK1 ferrule case, it's straightforward to stock one line item for every 6 A position in your panelboards.
