Eaton Specification Sheet - KAC-80
Feature: 600 V electrical rating with 80 A capacity → Business Impact: Protects medium voltage industrial circuits while handling typical startup surges, reducing the risk of downstream damage and unplanned downtime. Application: Suitable for 600 V distribution panels and motor control centers in manufacturing facilities. Feature: 200 kAIC interrupt rating → Business Impact: Greater fault current tolerance minimizes arc energy and equipment stress, improving safety margins and extending panel life. Application: Critical power feeds in high-energy fault environments such as large MCCs and switchgear bays. Feature: High speed operation (Bussmann Tron KAC) → Business Impact: Faster response times translate to shorter fault durations, enabling higher line availability and reduced maintenance windows. Application: Fast-clearing protection in busy production lines and automation racks. Feature: Blade end x blade end connection with stud mounting → Business Impact: Flexible installation options streamline retrofits and new builds, lowering field labor time and installation risk. Application: Retrofit projects and new panel designs requiring mixed connection styles. Feature: Non Indicating fuse indicator → Business Impact: Minimal external indicators reduce panel clutter; procurement teams can rely on upstream diagnostics for fault confirmation. Application: Control panels where visual indicator tamper is undesirable, paired with external monitoring schemes. Feature: UL Recognized and CE Marked → Business Impact: Global compliance supports international sourcing and qualified supplier status, reducing procurement cycle time. Application: Global manufacturing operations and multi-region deployments requiring regulatory alignment.

FAQs
KAC-80 supports blade end x blade end connections and a stud mounting method, offering flexibility for both retrofit and new panel builds. This enables quick substitutions in existing equipment without extensive rewiring, reduces field labor, and simplifies service in motor control centers and distribution panels.
The 200 kAIC interrupt rating means the fuse can safely interrupt very high fault currents, limiting arc energy and protecting upstream equipment. This is crucial in large electrical rooms and MCCs where fault currents can be substantial, reducing the risk of collateral damage and improving overall system uptime.
Yes. With 600 V rating, 80 A continuous current capability, and 200 kAIC interrupt rating, KAC-80 is well-suited for motor control centers and distribution panels in industrial environments. Its compact form, blade-end connections, and stud mounting support fast integration and reliable protection across common MCC configurations.
KAC-80 is UL Recognized and CE Marked, providing cross-regional compliance for North American and European markets. These certifications support supplier qualification and regulatory adherence, helping ensure procurement processes meet safety and performance requirements for industrial electrical protection.
By delivering rapid fault interruption (high-speed protection), reducing nuisance trips, and enabling straightforward installation, KAC-80 lowers downtime and maintenance costs. Its global certifications simplify sourcing, while its compact, versatile design reduces spare parts inventory and accelerates panel assembly, delivering measurable lifecycle savings.
