Special features
Non-indicating
Feature: 9 A amperage rating enables targeted motor protection while minimizing nuisance trips. Benefit: Improves uptime and reduces unplanned downtime in production lines. Application: Suitable for small-to-medium industrial motors in 600 V control circuits. Feature → Business Impact → Application: High inrush motor protection with a 200 kAIC interrupt rating provides rapid fault clearance, reducing arc energy and equipment damage. This is critical in high-short-circuit environments common in heavy industrial applications. Application: Motor starters and drive panels where fault current levels exceed standard protection. Feature: 600 V voltage rating ensures compatibility with typical industrial controls and motor circuits, simplifying panel design. Benefit: streamlines procurement and spare-part planning, enabling faster commissioning. Application: 3-phase motor control in manufacturing lines. Feature: Non-indicating fuse (no built-in visual status) lowers panel complexity and maintenance overhead. Benefit: reduces potential false indicators and simplifies wiring verification. Application: Compact control cabinets with space constraints. Feature: Certifications UL Listed and CSA Certified provide regulatory assurance. Benefit: supports compliance-driven projects and customer audits. Application: Electrical panels in regulated facilities and global deployments. Feature: Standard 5 in length and 0.81 in dimensions with 1.6 lb weight. Benefit: easy drop-in replacement in existing Bussmann Edison holders and compact layouts. Application: Retrofit projects and new-panel builds where space is at a premium.

FAQs
LESRK9I is designed for standard Bussmann Edison form factors with a 5 in length and 0.81 in cross-section. It fits typical Edison fuse holders used in 600 V motor control panels, simplifying retrofit projects and new installations alike.
Key specs include a 9 A amperage rating, 600 V voltage rating, and a 200 kAIC interrupt rating. It is UL Listed and CSA Certified, ensuring regulatory compliance for industrial panel builds.
Yes. The 9 A rating with a 200 kAIC interrupt capability supports motors with high inrush currents, providing rapid fault clearance while minimizing nuisance trips during startup.
The LESRK9I carries UL Listed and CSA Certified markings. These certifications confirm safety, reliability, and compliance with North American electrical standards, which is critical for panel audits and customer requirements.
Non-indicating fuses lack a built-in visual status indicator, so monitoring relies on system diagnostics or external indicators. This can reduce panel clutter and cost but requires regular electrical tests and alarms to confirm status, aiding proactive maintenance.
