Bussmann KAX-10 Eaton Series KAX Semiconductor Fuse, 1500 Vdc Non-Indicating

The Bussmann KAX-10 is part of Eaton's Bussmann series KAX line of semiconductor fuses, engineered to protect power semiconductors and DC circuits rated up to 1500 Vdc. This Non-Indicating fuse features a Standard speed characteristic, delivering fast, reliable interruption in high-voltage DC applications such as power conversion, inverter, and drive systems. Because semiconductor devices like thyristors, diodes, and IGBTs have very limited thermal overload capacity, a fuse purpose-built for this duty — like the KAX-10 — is essential to prevent damage during fault conditions. Its compact body makes it well suited for space-constrained enclosures and panel layouts where dependable overcurrent protection for semiconductor devices is critical to system uptime.

Key Features

  • Voltage Rating: 1500 Vdc rating supports protection of power semiconductors in high-voltage DC circuits and DC bus applications.
  • Series: Part of the Eaton Bussmann series KAX semiconductor fuse family, model KAX-10, purpose-built for power electronics protection.
  • Indication: Non-Indicating design without a visual blown-fuse indicator, suited to standard panel-mount and busbar-mount applications.
  • Speed: Standard speed characteristic tuned for coordinated protection of power semiconductor devices during overload and short-circuit events.
  • Compact Form Factor: Measures 2 in in height with a .56 in x .56 in body footprint and weighs .47 lb, suiting tight equipment layouts and high-density fuse blocks.
  • Semiconductor-Grade Design: Constructed specifically for the fast clearing and low let-through energy demanded by semiconductor protection, unlike general-purpose branch-circuit fuses.

Bussmann KAX-10 – Frequently Asked Questions

1) Can the Bussmann KAX-10 be used on a 1500 Vdc solar or battery storage DC bus?
Yes. The KAX-10 is rated 1500 Vdc, which covers 1500 V PV arrays, battery storage DC buses, and inverter DC links. It is a semiconductor fuse, so it is built for the fast clearing and low let-through energy that thyristors, diodes and IGBTs need, not for general branch-circuit duty.
2) Will the KAX-10 fuse show when it has blown?
No. The KAX-10 is a non-indicating fuse, so there is no pop-up pin or visual blown indicator and no provision for a microswitch trip indicator. If your panel needs blown-fuse annunciation, you will have to get it from monitoring elsewhere in the circuit or specify an indicating version of the series.
3) Can I use a standard branch-circuit fuse instead of a semiconductor fuse like the KAX-10?
Not for protecting power semiconductors. Devices like diodes, thyristors and IGBTs have very little thermal overload capacity, and a general-purpose branch-circuit fuse clears too slowly and lets through too much energy to save them. The KAX series is built for that duty specifically. A branch-circuit fuse still has its place protecting conductors and general loads, but it is not a substitute here.
4) Does the Bussmann KAX-10 carry a UL listing or other agency approvals?
For the KAX series, Bussmann directs compliance questions to the factory, and that is how the KAX-10 is published. If your submittal package needs specific agency documentation for this fuse, request it from Eaton for the exact model.
5) What is the speed characteristic of the KAX-10 and what does that mean for drive protection?
The KAX-10 uses a Standard speed characteristic within the semiconductor fuse family, tuned for coordinated protection of power semiconductor devices through both overload and short-circuit events. In a VFD or rectifier stack that means it will ride normal operating current while still clearing a fault fast enough to protect the devices.
6) What part number do I order for the Bussmann KAX-10?
The manufacturer part number is KAX-10, from Eaton's Bussmann series KAX semiconductor fuse line. It ships in standard packaging. Ordering by the full KAX-10 designation matters, since the amp ratings across the KAX family share the same prefix and the same 1500 Vdc rating.
