Eaton LESRK12I Fuse - UL Listed CSA Certified
Part Number: LESRK12I
Quick Summary
Eaton Edison LESRK12I fuse provides robust motor protection for industrial drives and control panels, guarding against faults while accommodating high startup inrush. Too often, motor protection either trips on startup or fails to clear faults quickly, leading to downtime and damaged equipment. Featuring UL Listed and CSA Certified approvals, plus a 12 A rating, 600 V rating, and a 200 kAIC interrupt rating, it meets demanding electrical codes. This fuse profile supports OEM and panel-builder workflows with a compact 5 in length and standard packaging, delivering reliable protection without complicating installation. By combining strong compliance with predictable protection, it helps reduce downtime and maintenance costs over the life of the equipment.

FAQs
The LESRK12I is designed for standard motor protection applications in 600 V systems with a 12 A rating and 200 kAIC interrupt capability. Its compact 5 in length and 0.81 in width allow easy installation in common control panels and enclosures, compatible with Bussmann/Edison fuse families for quick substitutions and streamlined spares management.
With a 12 A amperage rating and a 200 kAIC interrupt rating at 600 V, the LESRK12I interrupts fault currents rapidly while tolerating high inrush currents typical of motor startup. This combination protects windings from fault energy and minimizes nuisance trips that can halt production lines.
Yes. The LESRK12I fuse is intended for motor circuits up to 600 V, delivering high inrush protection and reliable fault interruption. Its UL Listed and CSA Certified status supports regulated environments, making it suitable for conveyors, pumps, and fans in manufacturing andē©ęµ setups where downtime costs are critical.
LESRK12I carries UL Listed and CSA Certified certifications, indicating compliance with recognized safety and performance standards. While the datasheet notes standard packaging and general information, these certifications help meet regulatory requirements during audits and supplier qualifications in many industrial sectors.
The device is specified with no warranty, so plan for proactive maintenance contracts or service-level agreements with your supplier. Its reliable interruption capability reduces motor damage and downtime, which lowers maintenance costs over the asset life. Regular diagnostics and stock of spare LESRK12I units can improve mean time to repair in high-demand lines.
