Eaton KAC-4 KAC High Speed Fuse - 200 kAIC UL Recognized
Part Number: KAC-4
Quick Summary
The Eaton KAC-4 high speed fuse protects industrial control circuits by interrupting faults quickly. Engineers often struggle to balance ultra-fast fault clearing with staying within 600 V systems and 4 A load conditions in tight panels. UL Recognized and CE Marked certifications support global safety compliance, while the 200 kAIC interrupt rating helps protect downstream equipment. With blade end x blade end connections and stud mounting, this fuse offers straightforward installation, consistent coordination with Eaton Bussmann Tron KAC devices, and reduced maintenance overhead. This combination supports faster commissioning, lower downtime, and a clearer path to global procurement across automation and power distribution projects.

Eaton Specification Sheet - KAC-4
Feature: 600 V rating paired with a 4 A amperage rating. Business Impact: Ensures compatibility with common control circuits while providing reliable protection against overcurrent events in standard industrial panels. Application: Ideal for automation equipment, control panels, and distributed power rails where compact protection is required. The result is improved system reliability and reduced risk of nuisance trips in scientific instrumentation and process automation. Feature: 200 kAIC interrupt rating. Business Impact: Capable of handling high fault current scenarios without cascading damage, preserving downstream components and conductive paths. Application: Motor drives, switchgear nodes, and main distribution trunks in manufacturing lines benefit from this robust current interruption. The outcome is extended equipment life and lower replacement costs in high-energy applications. Feature: Blade end x blade end connection, plus stud mounting. Business Impact: Simplifies replacement and delivers a secure, vibration-resistant fit in rugged environments. Application: Panel assemblies and equipment with blade-type holders and stud-mounted interfaces experience faster installation with consistent electrical contact and reduced torque-related issues. This translates to shorter maintenance windows and improved checklist compliance.Feature: Non-indicating fuse design. Business Impact: Reduces indicator-related false trips and lowers wiring complexity in status-monitoring schemes. Application: Control cabinets where status is tracked upstream or in centralized PLC dashboards benefit from clean wiring and reduced troubleshooting time. The business value is lower wiring costs and more straightforward diagnostics during preventive maintenance. Feature: Certifications and compliance (UL Recognized, CE Marked). Business Impact: Streamlines global procurement and regulatory acceptance for multinational projects. Application: Global manufacturing lines and international panel builds gain faster approval cycles, with consistent performance across sites. The overall benefit is a more predictable supply chain and lower total cost of ownership.

FAQs
The KAC-4 uses blade end x blade end connections and stud mounting, enabling straightforward retrofits in standard Eaton Bussmann Tron KAC assemblies. Its compact 0.5 in depth and 0.5 in width fit many 3U panel spaces, reducing enclosure redesign. This compatibility minimizes installation time and ensures reliable, repeatable protection across multiple cabinet designs.
The KAC-4 is rated for 600 V and 4 A with a 200 kAIC interrupt rating. This combination supports fast fault clearing in typical control circuits while tolerating high fault currents without damage to upstream equipment. Designers should account for these values to ensure coordination with upstream fuses or breakers and to protect downstream power electronics.
Yes. The KAC-4 carries UL Recognized and CE Marked certifications, streamlining procurement for global deployments. This helps satisfy safety and regulatory requirements in North America, Europe, and many other regions, reducing the need for alternative part studies or additional documentation.
Non-indicating fuses reduce wiring complexity and avoid false fault visuals within status dashboards. They are ideal where fault status is monitored remotely or via separate indicators, such as PLC fault logs or centralized control systems, improving diagnostic workflows and minimizing dashboard clutter.
The KAC-4 delivers fast protection with a robust 200 kAIC rating, supporting reduced downtime and equipment damage in fault events. Its straightforward installation and standardized Eaton Bussmann Tron compatibility lower maintenance time, while UL CE compliance broadens procurement options, contributing to lower lifecycle costs and faster project timelines.
