Bussmann KAX Series Semiconductor Fuse

Bussmann KAX-1 Eaton Series Semiconductor Fuse, 1A

The Bussmann KAX-1 is an Eaton Bussmann series KAX semiconductor fuse rated at 1 A, engineered to deliver fast-acting, current-limiting overcurrent protection for sensitive power semiconductor devices such as SCRs, thyristors, diodes, and other solid-state components used in industrial power conversion equipment. Compact dimensions of 2 in in height by .56 in in width by .56 in in depth allow this fuse to fit tightly spaced fuse blocks, fuse holders, and power electronic assemblies where board and panel space is at a premium. As part of the widely specified Bussmann KAX series, the KAX-1 is built to help protect costly semiconductor components from short-circuit and overload damage while supporting reliable, code-compliant performance in demanding industrial power circuits.

Key Features

• Amperage Rating: 1 A precise current rating engineered for accurate, repeatable protection of low-current semiconductor circuits without nuisance opening.
• KAX Series Construction: part of the Bussmann KAX semiconductor fuse series, purpose-built to safeguard SCRs, thyristors, and other solid-state power devices from damaging fault currents.
• Compact Footprint: measures 2 in in height, .56 in in width, and .56 in in depth, making it well suited to compact fuse blocks, holders, and space-constrained control panels.
• Lightweight Design: weighs just .47 lb, simplifying handling, stocking, and installation for maintenance and panel-build teams.
• Fast-Acting Protection: semiconductor-class fuse construction is designed to open quickly under fault conditions, helping limit let-through energy to downstream power electronics.
• Eaton Engineering: manufactured under the Eaton Bussmann brand, a name long trusted for circuit protection components across industrial and commercial power systems.
