Eaton KAC-450 High Speed Fuse - 600 V UL Recognized
Part Number: KAC-450
Quick Summary
Eaton KAC-450 high speed fuse protects critical circuits in industrial power distribution and motor drives. Selecting protection that responds quickly without causing nuisance trips in compact panels remains a common challenge. This device is CE Marked and UL Recognized, reinforcing compliance for global installations. By using the Bussmann series Tron KAC fuse with blade end x blade end terminals and stud mounting, you gain reliable protection, easier installation, and lower total cost of ownership. Designed for 600 V systems, it handles up to 450 A with a 200 kAIC interrupt rating, ensuring selective coordination with upstream protection. In practice, engineers report faster panel commissioning, reduced warranty exposure, and predictable protection across load profiles, aligning with uptime targets and safety standards.

Eaton Specification Sheet - KAC-450
Feature to Benefit to Application: 600 V system rating with a 450 A amperage rating delivers fast fault clearing and minimizes damage to downstream equipment, reducing downtime and maintenance costs in motor drives and switchgear assemblies. This level of interrupt capability (200 kAIC) supports selective coordination inhigh-energy feeders, which translates to safer operation and fewer cascading outages in industrial power panels. Feature to Benefit to Application: Blade end x blade end connections complemented by stud mounting provide flexible installation options and compatibility with common Eaton power distribution hardware, enabling quick retrofits in existing enclosures and improving time-to-commission for new lines. Feature to Benefit to Application: Non Indicating fuse status means lower part counts and simpler stock management, while wiring diagrams and proper ancillary indicators can be added to monitor critical feeders, helping maintenance teams optimize preventive programs. Feature to Benefit to Application: UL Recognized and CE Marked compliance ensures regulatory readiness for global deployments, facilitating procurement, quality audits, and cross-border project execution. Feature to Benefit to Application: 6.25 in length and 3.29 lb weight offer predictable compatibility with standard fuse blocks and panel spaces, supporting consistent field installations and reducing the risk of fitment issues during upgrades or expansions.

FAQs
KAC-450 uses blade end x blade end connections with stud mounting, offering flexible installation for both new panels and retrofits. This combination makes it compatible with standard Eaton distribution hardware and busbar configurations, simplifying wiring diagrams and reducing installation time in industrial control panels.
KAC-450 is rated for 450 A with an interrupt rating of 200 kAIC at a voltage rating of 600 V. This enables rapid fault interruption for high-energy circuits, supports selective coordination in motor drives and power panels, and helps minimize damage to downstream equipment during fault events.
Yes. The KAC-450 is CE Marked and UL Recognized, indicating compliance with European and North American safety standards. This supports global deployments in industrial environments, streamlines supplier qualification, and aligns with cross-border procurement requirements.
As a non-indicating fuse, KAC-450 requires external status monitoring or indicators for live condition checks. Plan for auxiliary signaling or periodic measurement to verify ongoing protection of critical feeders, and ensure your maintenance schedule accounts for proactive panel checks and spare part readiness.
The 450 A, 600 V protection with UL Recognized and CE Mark ensures reliable, compliant protection that reduces nuisance trips and downtime. Its robust interrupt rating and flexible mounting simplify procurement, installation, and long-term asset protection, delivering quicker commissioning, improved uptime, and lower total cost of ownership for high-energy industrial applications.
