Eaton Specification Sheet - KEX
Feature 200 kAIC interrupt rating at 600 Vac → Business Impact Provides high-energy fault protection that minimizes conductor damage and arc-flash risk, reducing unplanned downtime. Application Ideal for 600 VAC feeders in motor control centers and switchgear where fault energy is a concern. The compact form factor supports easier panel layouts and faster installation, lowering field labor costs. Feature Copper wire construction (#4/0 AWG) → Business Impact Ensures reliable, low-resistance connections with durable conductivity, improving long-term performance. Application Well-suited for copper feeder runs in industrial controls and distribution panels where high current handling is required. Feature Compression rod x tubular end connection → Business Impact Delivers secure, vibration-resistant terminations that stay tight under harsh conditions, reducing maintenance calls. Application Ideal for rugged industrial environments with frequent inspections or re-terminations. Feature Non-indicating fuse indicator → Business Impact Simplifies device selection in dense panels by relying on periodic electrical testing rather than visual indicators, cutting maintenance time. Application Useful in installations where independent diagnostic routines are embedded in the control system. Feature RoHS Compliant → Business Impact Supports regulatory compliance and environmental stewardship, reducing material handling risk. Application Aligns with sustainability programs across manufacturing facilities and lowers compliance overhead. Feature Lightweight design (0.1 lb) → Business Impact Eases handling during installation and replacements, lowering labor intensity and installation time. Application Beneficial for in-panel upgrades or retrofits where weight reduction matters. Feature 1.44 in L x 1.44 in W x 7.88 in H footprint → Business Impact Enables space-efficient mounting in crowded enclosures, freeing space for wiring and other components. Application Ideal for compact control panels and limited-clearance installations. Feature Copper cable with 1.75 inch length for #4/0 AWG → Business Impact Ensures robust power delivery with proven conductor material, improving protection performance and reliability. Application Suitable for direct use with large-diameter copper conductors in Eaton Bussmann KEX configurations.
