Eaton KAC-125 High Speed Fuse - UL Recognized
Part Number: KAC-125
Quick Summary
The Eaton KAC-125 high speed fuse provides fast-acting circuit protection for industrial DC power systems. Engineers often grapple with nuisance trips or protection that is too slow or undersized, leading to downtime and equipment damage. UL Recognized and CE Marked certifications underpin regulatory compliance and safe field replacements, with a 200 kAIC interrupt rating that supports robust fault protection. Designed for Boschmann Tron KAC style applications, this fuse aligns with blade end x blade end configurations and stud mounting, reducing spare parts drift while delivering predictable protection margins for OEMs and maintenance teams alike.

Feature: 125 A amperage rating provides appropriate protection for medium to high-current DC feeders. Business Impact: Enables precise protection without unnecessary discrepanies, reducing mean time to repair and extending component life in power rectifier circuits. Application: Ideal for industrial rectifier fuses and DC bus protection in motor drives and power supplies. Feature: 200 kAIC interrupt rating ensures high fault current withstand capability. Business Impact: Enhances system reliability by tolerating surge events and minimizing collateral damage to upstream equipment. Application: Suitable for indoor and compact power distribution in high-current environments where rectifier assemblies are common. Feature: Non Indicating, blade end x blade end connections with stud mounting. Business Impact: Simplifies installation and retrofits by matching standard Bussmann Tron families while enabling solid mechanical mounting in control panels. Application: Perfect for retrofit projects and OEM assemblies with limited space or standardized blade-fit components. Feature: UL Recognized and CE Marked compliance. Business Impact: Streamlines procurement and regulatory approvals, reducing project risk and audit findings. Application: Required for global deployments in regulated facilities and equipment used across North America and Europe. Feature: Compact, exacting dimensions (5.99 in length, 1.72 in width, 1.74 in height). Business Impact: Fits into tight enclosures and minimizes footprint while maintaining robust protective performance. Application: Suitable for enclosure layouts with strict space constraints in rectifier modules and power assemblies.
