Special features
Non-indicating, High in-rush current motor protection
Feature – 60 A, 600 V, 200 kAIC interrupt rating provides robust short-circuit protection while minimizing nuisance trips. Business Impact – protects expensive motors and drives without sacrificing startup performance, reducing unplanned downtime and extending motor life in 600 V systems. Application – ideal for motor control centers and industrial drives that demand reliable protection at a standard 60 A rating. The upgrade path is straightforward due to a familiar Edison form factor. Feature – Non-indicating fuse reduces visual indicators in dense panels, freeing space for critical wiring and indicators. Business Impact – simplifies panel design and maintenance, lowering inspection time and error risk during replacements. Application – well-suited to compact switchgear and control panels where indication is managed elsewhere. Feature – High inrush current motor protection ensures startups are protected even under surge conditions. Business Impact – prevents premature tripping on motor starts, enabling smoother operations and improved line reliability. Application – particularly beneficial for fan motors, compressors, and variable-frequency drive applications. Feature – Certifications UL Listed and CSA Certified provide regulatory assurance. Business Impact – supports compliant procurement and audit readiness, streamlining vendor qualification. Application – essential for regulated industries and multinational installations. Feature – Compact, standard Edison format with a 5.5 in length and 1.06 in width enables easy retrofit. Business Impact – reduces panel modification cost and installation time, improving project ROI. Application – ideal for OEMs and upgrade projects seeking minimal layout disruption.

FAQs
LESRK60 is designed for standard Edison-compatible fuse blocks and 600 V motor circuits. Verify matching fuse holders, use appropriate 5.5 in length devices, and follow NEC/UL wiring practices. The non-indicating design helps conserve panel space, but ensure wiring and clearance meet your panel layout and cooling requirements.
The LESRK60 is rated for 60 A continuous current, 600 V maximum voltage, and 200 kAIC interrupt capacity. It is a Class RK1 fuse with non-indicating status, designed for high inrush motor protection in standard industrial applications.
Yes. The 200 kAIC interrupt rating supports high-inrush startup conditions common with motors and drives, reducing nuisance trips while maintaining strong short-circuit protection. For optimal results, pair with appropriate contactors and drive settings to balance protection and startup performance.
LESRK60 is UL Listed and CSA Certified, which confirms adherence to safety and performance standards recognized in North America. These certifications support procurement, audits, and regulatory compliance, easing supplier qualification and ensuring system safety across facilities.
Using LESRK60 can reduce downtime from nuisance trips during motor startups and provide predictable replacement cycles due to its standardized Edison form factor. While maintenance needs are similar to other fuses, the reliable 60 A/600 V protection and high interrupt rating contribute to lower total cost of ownership over motor-driven equipment lifecycles.
