Eaton KAC-3 High Speed Fuse - UL Recognized, 200 kAIC
Part Number: KAC-3
Quick Summary
The Eaton KAC-3 high speed fuse protects power electronics and control circuits in industrial drives and rectifier assemblies. Sizing correctly and avoiding nuisance trips is a common challenge that disrupts uptime and increases maintenance costs. UL Recognized and CE marked provide regulatory confidence, while a 200 kAIC interrupt rating ensures fast, safe fault clearing. As part of Eaton Bussmann’s Tron KAC family, it delivers reliable protection with a compact footprint that simplifies panel design. This translates to reduced downtime, lower energy waste, and safer, more predictable protection of critical power paths. The datasheet provides mounting, wiring, and fusing guidelines for consistent performance.

FAQs
Install the KAC-3 using blade end x blade end connections or mount it using the stud mounting option. Verify the fuse holder or panel cutout matches the 0.5 in depth and 0.5 in width footprint, and ensure secure electrical contact. Because this fuse is non-indicating, confirm status via your system's monitoring or diagnostic interface and consult the datasheet for torque specs and clearance requirements.
The KAC-3 fuse provides a 3 A amperage rating with a 200 kAIC interrupt rating. This combination enables fast fault clearing in power electronics circuits, reducing arc energy and protecting downstream components in rectifiers, drives, and power supplies. Always verify operating conditions align with the datasheet specifications for voltage and environment.
KAC-3 is well suited for rectifier modules, industrial drives, and power-supply protection in control panels. Its compact 0.5 x 0.5 inch footprint with blade end connections and stud mounting supports tight panel layouts, while its 3 A rating and 200 kAIC interrupt rating provide reliable protection for small to mid-size power electronics in manufacturing environments.
Yes. The KAC-3 fuse is UL Recognized and CE Marked, ensuring compliance with safety and regulatory requirements for global industrial equipment. This status supports expedited qualification for equipment across North America and Europe, reducing time-to-market for OEM assemblies and ensuring consistent protection across the Tron KAC family.
Because the KAC-3 is Non Indicating, supervision relies on your system’s fault-logging or indicator signals. Plan for spare fuses and standard stock based on your maintenance window. The blade end x blade end connections and stud mounting simplify replacement, while the compact form factor minimizes downtime during field swaps and service intervals.
