Bussmann KTN-S-30 – Frequently Asked Questions

1) What amp rating is the Bussmann KTN-S-30 cartridge fuse?
The KTN-S-30 is a 30A cartridge fuse. Amp rating has to match the circuit it protects, so it goes into panelboard circuits sized for 30 amps, not as a general substitute for whatever fuse happens to be in the holder.
2) Where is the Bussmann KTN-S-30 fuse used?
Panelboards are the stated application. In practice that means electrical distribution panels and the compatible fuse holders and disconnect switches inside them, in commercial and industrial installations. It is a one-time overcurrent device, so once it opens it gets replaced rather than reset.
3) Do I need special tools to install a KTN-S-30 cartridge fuse in a panelboard?
No tools are needed for the fuse itself. The cylindrical cartridge body drops into a compatible panelboard fuse holder, so a maintenance tech can swap it during troubleshooting or scheduled replacement with the circuit de-energized. Fuse pullers are the usual way to get a cartridge out of a live-front holder.
4) Is the KTN-S-30 a resettable breaker or a one-shot fuse?
It's a fuse, not a breaker. Contractors and maintenance teams specify the KTN-S-30 when a panelboard circuit calls for a drop-in overcurrent protection component rather than a resettable device, which means keeping replacements on hand for that circuit.
5) Is KTN-S-30 the actual Bussmann part number to order?
Yes, KTN-S-30 is the Bussmann manufacturer part number and the model designation for this 30A cartridge fuse. Distributors can order against that number directly.
6) How much does the Bussmann KTN-S-30 fuse weigh for MRO stocking?
About .35 lb each. Light enough that a maintenance crew can carry spares on the cart, and worth stocking in multiples since a fuse is consumed when it clears a fault.
