Bussmann KTS-R-4 – Frequently Asked Questions

1) Will a Bussmann KTS-R fuse fit my existing Class RK5 fuse clips and rejection holders?
The KTS-R is a Class RK1 fuse, and Class R fuses (both RK1 and RK5) share the same dimensions and the same annular ring on the blade that works with Class R rejection clips. So a KTS-R drops into a Class R rejection holder and into standard non-rejecting clips of the same amp range. Going the other direction does not work: a non-Class-R fuse of the same amp rating will not fit a Class R rejection holder. The 110 A KTS-R-110 measures 9.63 x 1.5 x 1.5 inches.
2) Is the Bussmann KTS-R a fast-acting or time-delay fuse, and can I use it for motor circuits?
LIMITRON KTS-R is a fast-acting fuse with no intentional time delay. That makes it suited to protecting non-motor loads and circuits where inrush is minimal, plus use as a current-limiting fuse ahead of equipment with a short-circuit rating. For motor branch circuits, where locked-rotor inrush would blow a fast-acting fuse on every start, you want a dual-element time-delay Class RK1 instead, such as Bussmann LOW-PEAK LPS-RK in the same 600 V Class R case size.
3) What is the interrupting rating of the Bussmann KTS-R, and is it enough for a high available-fault panelboard?
The KTS-R interrupts 200 kAIC at 600 Vac. That covers essentially any available fault current you will calculate on a commercial service, and because it is a current-limiting Class RK1 fuse it also reduces let-through energy to downstream equipment. It is listed for panelboard use.
4) What amp ratings does the Bussmann KTS-R fast-acting fuse come in?
Four amp ratings are offered: 1 A (KTS-R-1), 4 A (KTS-R-4), 90 A (KTS-R-90) and 110 A (KTS-R-110). All share the 600 V, Class RK1, 200 kAIC rating, so you can mix ratings across a facility without changing holder type.
5) Does the Bussmann KTS-R have a blown-fuse indicator?
No. The KTS-R is non-indicating, so there is no visual flag or pop-out pin to tell you which leg opened. On a three-phase panel you will need to meter each fuse or use an indicating holder if at-a-glance troubleshooting matters to your maintenance crew.
6) How many fuses do I need for a three-phase 480V disconnect using KTS-R?
Three, one per phase. KTS-R fuses are sold individually by amp rating, so a three-pole 480 V fused disconnect or panelboard needs three of the same catalog number, and most maintenance departments stock a fourth as a spare since the fuses are non-indicating and get replaced as a set.
7) Is the KTS-R a single-element or dual-element fuse?
Single element. The KTS-R is built with one element, which is what gives it its fast-acting characteristic and current-limiting performance on short circuits, and also why it has no time delay for inrush loads.
8) Are these genuine Eaton Bussmann fuses, and do they carry CE marking?
These are genuine Eaton Bussmann LIMITRON KTS-R fuses ordered by the factory part number, for example KTS-R-90 for the 90 amp. The fuse is CE Marked and ships in Bussmann's standard packaging.
