Eaton Specification Sheet - KAC-90
The KAC-90 provides a 90 ampere rating paired with a 200 kAIC interrupt capability, delivering immediate fault clearance to protect valuable drives and control electronics from damaging short circuits. In manufacturing lines, this translates to reduced downtime and fewer component replacements after faults, helping maintain line throughput and lower operating costs. The blade end x blade end connections with stud mounting offer a versatile fit in compact control panels, while the 1 in length, 5 in height, and 1 in width create a predictable footprint that simplifies enclosure planning and replacements in retrofit projects. Certified with UL Recognized and CE Marking, the fuse supports regulatory compliance and accelerates procurement approvals in global factories. The non-indicating status and standard packaging reduce maintenance checks and inventory complexity, enabling faster replacements during scheduled outages. Designed for the Bussmann Tron line, it integrates with existing protective assemblies and resolver-less diagnostics for routine service windows. The lightweight 0.27 lb weight and standard packaging further minimize shipping and handling costs while preserving rugged protection.

FAQs
Installation considerations for the Eaton KAC-90 high speed fuse include confirming blade-end x blade-end connectors match your fuse holder and ensuring a compatible stud-mounting footprint. The 1 inch by 5 inch profile fits common Bussmann Tron housings and enables straightforward retrofits in existing control panels without major enclosure remodeling. Use proper torque on mounting studs to maintain reliable electrical contact.
The KAC-90 features a 200 kAIC interrupt rating, designed to safely interrupt high fault currents without arcing or damage. This is critical in systems with large motor starts and power distribution where fault currents can spike rapidly. Selecting a fuse with this rating reduces collateral damage and simplifies upstream protection coordination, improving overall system reliability.
Yes. The KAC-90 provides blade end x blade end connections and a stud mounting option, offering flexible installation in various panel configurations. This dual-connection capability supports both plug-in fuse holders and fixed-mounting in control cabinets. Always verify your panel busbar spacing and torque requirements per the Eaton datasheet for optimum performance.
KAC-90 is UL Recognized and CE Marked, meeting global safety and electrical protection standards. UL recognition supports reliable performance in North American systems, while CE marking demonstrates compliance with European directives. Together they facilitate procurement approvals, reduce qualification time, and help meet industry requirements for control panels and machinery in regulated environments.
Using the KAC-90 high speed fuse can lower maintenance intervals by delivering rapid fault clearing and protecting critical loads, reducing downtime and spare parts costs. Its compact footprint and non-indicating design simplify stocking and field replacements, while UL and CE certifications support smoother manufacturing approvals and ongoing regulatory compliance, delivering measurable ROI in high-demand panel environments.
