Bussmann KAX-15 – Frequently Asked Questions

1) Can the Bussmann KAX-15 fuse be used on a 1500 Vdc DC bus?
Yes. The KAX-15 is rated 1500 Vdc, so it is intended for high-voltage DC circuits such as power conversion equipment, rectifier sections, and DC distribution. It is a DC-rated semiconductor fuse, so do not substitute it into an AC branch circuit application expecting an equivalent AC rating.
2) Is a semiconductor fuse like the KAX-15 the right choice, or should I use a standard branch-circuit fuse?
A semiconductor fuse is the right choice when you are protecting the power electronics themselves. The KAX series is built to clear fast enough to save SCRs, diodes, and thyristors from overcurrent and short-circuit damage. A standard branch-circuit or time-delay fuse is sized to protect conductors and tolerate motor inrush, and it will generally let a semiconductor fail first. Use the semiconductor fuse at the device, and conventional fuses for feeder and branch protection.
3) Will a KAX-15 semiconductor fuse fit in a tight enclosure or fuse block?
Body dimensions are 2 in height with .56 in length/depth and .56 in width, so it is a slim cylindrical-footprint fuse that drops into space-constrained enclosures. Measure your holder opening against the .56 in cross-section before committing.
4) Does the KAX-15 have a blown-fuse indicator for maintenance checks?
No. The KAX-15 is a non-indicating fuse, so there is no visual pin or flag to show it has opened. Crews troubleshooting a drive or rectifier will need to meter across it or use a monitored holder. If your maintenance procedure depends on walk-by visual inspection, specify an indicating version of the series instead.
5) Is the Bussmann KAX-15 suitable for solar inverter and renewable energy DC circuits?
Yes, within its 1500 Vdc rating. Typical uses named for the KAX series include renewable energy and power electronics installations, high-voltage DC power conversion, and DC switchgear, all of which line up with 1500 V PV and storage architectures. Match the ampere rating and the application's required interrupting duty to your engineered design.
6) What exactly do I order to get this Bussmann fuse, and how is it packaged?
Order by manufacturer part number KAX-15 from Eaton Bussmann. It ships in the series standard packaging, which keeps reorder quantities consistent for MRO stocking.
7) How heavy is the KAX-15, and does it need support in the holder?
It weighs about .47 lb, light enough that a standard clip or stud mount carries it without additional bracing. At that weight and a 2 in body, handling and stocking are straightforward for a spares crib.
