Bussmann KTK-4 – Frequently Asked Questions

1) What amp ratings does the Bussmann KTK Limitron fuse come in?
The KTK Limitron fast-acting fuse is offered in 4 A (KTK-4), 6 A (KTK-6), and 7 A (KTK-7). All three share the same 600 V rating and the same ferrule end x ferrule end body, so stepping between them is purely an amp-rating decision.
2) Is the KTK rated for a 600 volt control circuit with high available fault current?
It is. The KTK carries a 600 V rating with a 100 kAIC interrupting rating at 600 Vac, so it holds up on control, lighting, and meter circuits fed from service points with high available short circuit current.
3) Should I use a fast-acting midget fuse or a time-delay fuse for my control transformer circuit?
Fast-acting is what the KTK is. It clears quickly with no intentional time delay, which suits control circuits, lighting circuits, and meter circuits where there is no inrush to ride through. If you are protecting a motor or a transformer primary that draws a heavy inrush on energization, a fast-acting midget fuse will nuisance-open and you want a time-delay type instead.
4) Does the KTK fuse have a blown-fuse indicator?
No. The KTK is non-indicating, so there is no pop-up pin or window to show it has opened. On a panel where techs need to spot a blown fuse without pulling it, you will want an indicating type or an indicating fuse holder instead.
5) What are the KTK fuse endcaps and body made of, and will they hold up in a damp mechanical room?
Endcaps are nickel-plated bronze and the barrel is a melamine tube. The nickel plating resists corrosion at the clip contact, which matters in a humid plant or mechanical room where bare brass ferrules can oxidize and cause a hot contact.
6) Is this a genuine Eaton Bussmann KTK fuse or an equivalent?
Genuine Bussmann. The parts carry the Eaton Bussmann KTK Limitron part numbers directly, for example KTK-4, and ship in standard packaging rather than a repack.
