Bussmann KAB-25 – Frequently Asked Questions

1) What amperage is the Bussmann KAB-25 Tron fuse rated for?
The KAB-25 is a 25 amp high-speed fuse in the Eaton Bussmann Tron KAB family. If your coordination schedule calls for a different rating, you need a different KAB part number, not this one, since the fuse element is rated and sized for 25A only.
2) Will the KAB-25 fuse fit my existing fuse block or holder?
The body measures 1.98 in by .5 in by .5 in, so it is a compact cylindrical-footprint fuse sized to drop into existing Tron KAB fuse mountings. Measure the clip spacing or holder cavity in your block against those dimensions before you order; if your block was built for a different Bussmann series, the KAB body will not seat correctly.
3) Can I use the Bussmann KAB-25 as a straight replacement for a blown KAB fuse in a control panel?
Yes, for an existing Tron KAB mounting at the same 25A rating it is a direct replacement. Pull the old fuse, confirm the printed rating on its body reads 25A, and seat the new one in the same clips. If the original was a different amperage, replace like for like rather than substituting this rating.
4) Is a high-speed fuse like the KAB-25 the right choice, or should I use a time-delay fuse?
High-speed (fast-acting) fuses such as the Tron KAB-25 clear quickly on a fault, which is what you want protecting equipment and wiring that cannot tolerate let-through energy. A time-delay fuse is the better pick where you need to ride through motor inrush on starting without nuisance opening. On a motor circuit, that usually means time-delay ahead of the motor and a fast-acting fuse where downstream equipment protection is the priority.
5) What is the Bussmann KAB-25 part number and manufacturer?
The manufacturer part number is KAB-25, from Bussmann by Eaton, in the Tron KAB high-speed fuse series. That is the number to quote when ordering or cross-referencing a panel schedule.
6) What is the Bussmann KAB-25 typically used for?
It is specified for industrial and commercial overcurrent and short-circuit protection: motor control centers, power distribution and panelboards, switchgear maintenance, and fuse block or holder replacement on both retrofit and new construction work. It is meant to be applied by qualified electrical staff as part of a coordinated overcurrent scheme, not dropped in arbitrarily.
7) How much does the KAB-25 fuse weigh for shipping or a stocking kit?
Each KAB-25 weighs .4 lb, light enough that a maintenance crew can carry a handful of spares in a kit without much thought. Useful if you are standardizing spare fuses across several panels.
