The LESRK30I fuse is rated at 30 A with a 200 kAIC interrupt rating at 600 V. This high interrupt capacity enables rapid fault clearance in motor circuits, reducing fault energy and protecting upstream components, which translates to longer motor life and lower repair costs in heavy-use applications such as conveyors and pump stations. Inrush protection is specifically designed to tolerate the surge currents seen in high-demand drives, improving system reliability and reducing nuisance trips that can halt production. CSA Certified and UL Listed certifications provide compliance confidence for North American installations, helping meet safety and procurement requirements without additional validation steps. The device is designed as a non-indicating fuse, minimizing panel clutter and simplifying maintenance routines, while still delivering dependable protection in standard Edison fuse blocks. Compatibility with Edison-style fuses and standard packaging enables faster stocking, easier replacement, and more predictable maintenance windows. Industry context shows that properly rated fuses improve selectivity with upstream protection and can lower total cost of ownership by reducing unplanned downtime and energy waste.

FAQs
The LESRK30I is designed for standard Edison fuse blocks and fits typical motor control center configurations. Begin by ensuring the panel is de-energized, verify enclosure clearance, and align the fuse with the correct bus connections. Use the manufacturer-supplied mounting hardware and torque guidelines per the Eaton specification sheet to secure the fuse. After installation, perform a visual check for proper seating and confirm wiring is within the 600 V system limits. Finally, restore power and verify no nuisance trips occur under normal operating inrush conditions.
LESRK30I is rated at 30 A with a 200 kAIC interrupt rating and a 600 V maximum operating voltage. These ratings mean the fuse can safely interrupt high fault currents while protecting motor circuits during startup surges. The 200 kAIC capability provides robust protection for motors and drive electronics in industrial environments, reducing the likelihood of collateral damage and contributing to overall system reliability.
Yes. The LESRK30I is specifically designed for high inrush current motor protection, offering a 200 kAIC interrupt rating at 600 V. This combination supports reliable startup and fault clearance for motors in heavy-duty applications like conveyors, pumps, and fans, while minimizing nuisance tripping and ensuring consistent uptime.
The LESRK30I carries CSA Certification and UL Listing, confirming adherence to recognized safety standards for electrical protection devices in North America. These certifications simplify procurement, support regulatory compliance, and reduce vendor qualification time for projects requiring validated electrical protection components in 600 V systems.
The LESRK30I provides predictable protection with a compact, non-indicating design that reduces panel clutter and simplifies replacement. By preventing motor faults from propagating to drive electronics, it lowers downtime, extends motor life, and improves overall equipment effectiveness (OEE). In addition, its CSA UL certifications streamline compliance and procurement, contributing to lower total cost of ownership over the equipment’s lifecycle.
