Bussmann KAW-20 – Frequently Asked Questions
1) Will a Bussmann KAW-20 fuse fit in a compact fuse block or holder?
The KAW-20 semiconductor fuse measures 1.5 in by .36 in by .36 in, so it drops into tight fuse holder and fuse block positions sized for a small cylindrical body. Measure the clip spacing and cavity depth in your block against those three numbers before you commit, since the body is only .36 in across in both directions.
2) Can I use a semiconductor fuse like the Bussmann KAW-20 instead of a standard branch circuit fuse?
No. The KAW-20 is a semiconductor (fast-acting) fuse built to protect solid-state devices such as SCRs, diodes, and thyristors by opening quickly and limiting let-through energy. That is a different job from branch circuit or motor overload protection, where a time-delay class fuse is used so motor inrush does not blow it. Use the KAW-20 on the semiconductor side of a drive or rectifier, not as a general branch protection substitute.
3) What is the Bussmann KAW-20 rated for in amps, and where is that rating used?
Rated 20 A. On a drive or rectifier, that rating is matched to the semiconductor device's fault withstand rather than to the motor nameplate, so confirm the 20 A fuse is the value the drive or power conversion equipment manufacturer calls out for that SCR or diode leg.
4) Is the Bussmann KAW-20 the right fuse for a VFD or rectifier assembly?
Yes, that is what the Eaton Bussmann series KAW is built for. Typical uses are variable frequency drives, rectifier and power conversion equipment, industrial motor drive and control systems, and panel or fuse block assemblies that need a compact fuse. It protects the solid-state components in those assemblies from fault current.
5) What exact part number should I order for the 20 amp Bussmann KAW semiconductor fuse?
Order by manufacturer part number KAW-20, Bussmann by Eaton, series KAW. The amp rating is in the suffix, so a different amperage in the same family carries a different number after the dash.
6) How much does a Bussmann KAW-20 fuse weigh for stocking and panel load purposes?
Each KAW-20 weighs .1 lb, so holding a few spares on the truck or in an MRO crib adds essentially nothing, and a bank of them puts no meaningful load on a panel or drive assembly.
