Eaton LESRK350 Fuse - 200 kAIC Class RK1, UL Listed
Part Number: LESRK350
Quick Summary
The Eaton LESRK350 fuse provides reliable motor circuit protection for industrial motor drives. But inrush spikes and improper fuse ratings often trigger nuisance trips, causing costly downtime. UL Listed and CSA certified with RoHS compliance ensure safe, regulatory-ready integration in control panels. Engineers benefit from predictable coordination with drive systems, reduced maintenance, and faster compliance reporting. The device delivers up to 200 kAIC interrupt rating and 600 V, enabling robust protection across motor starters, not just fuses. With standard 1-pack packaging and a non-indicating design, replacement during scheduled maintenance becomes straightforward. Its RoHS compliance further supports sustainable facilities by reducing hazardous waste considerations during disposal.

Special features
Non-indicating, High in-rush current motor protection
Non-indicating design and high inrush protection keep motor circuits safe without unnecessary panel indicators. This translates to fewer nuisance trips during motor start-up and dramatically reduced unplanned downtime in manufacturing lines. The LESRK350 is ideal for industrial motor protection in MCCs and drive panels, coordinating with Class RK1 fuses and delivering reliable protection for large induction motors in demanding applications such as conveyors, pumps, and fans.\n\nRated at 350 A with a 600 V rating and 200 kAIC interrupt capacity, the LESRK350 clears faults quickly while maintaining service continuity for high-powered drives. This combination supports safe energization of motors in process lines and packaging equipment, even under short-circuit events, reducing damages to equipment and minimizing energy waste.\n\nRoHS compliant, UL Listed, and CSA Certified, this fuse meets global safety and environmental standards. Certifications simplify regulatory audits, shorten panel approvals, and streamline supplier qualification for OEMs and integrators. With these credentials, engineering teams can source confidently across multi-site facilities, knowing the protection device aligns with common procurement and compliance requirements.\n\nStandard packaging and a compact form factor aid fast stocking and replacement in maintenance workflows. The LESRK350 measures 11.63 inches long with a 2.36-inch width and height, and weighs 2.36 lb, making it easy to handle in crowded electrical rooms. Electrically isolated end caps simplify installation and minimize the risk of accidental contact during panel assembly.\n\nCompatibility with Eaton Edison Bussmann fuse lines supports streamlined procurement and spare-part planning across plants. Its non-indicating design reduces on-panel indicators, while still delivering high-current protection critical for motor feeders, MCCs, and drive systems. For engineers facing heavy throughput and tight uptime targets, LESRK350 provides predictable performance, quick replacements, and a clear path to compliant, maintainable protection.

FAQs
LESRK350 is designed for Eaton Edison RK1 fuse blocks used in motor control centers and drive panels. It fits standard fuse holders and is compatible with non-indicating end caps, enabling straightforward replacement in MCCs and panel boards. Ensure the circuit protection aligns with a 350 A rating, 600 V environment, and a 200 kAIC interrupt rating for safe operation of large motors.
LESRK350 provides a 200 kAIC interrupt rating at 600 V, enabling fast clearance of short-circuit faults in heavy motor circuits. This rating supports dependable motor protection for large induction motors and drive panels, while maintaining service continuity during normal start-up and high inrush conditions. It is rated at 350 A to match demanding feeders.
Yes. The LESRK350 is RoHS compliant and carries UL Listed and CSA Certified marks, ensuring safety, environmental responsibility, and regulatory acceptance across North American facilities. These certifications simplify procurement audits, support compliance documentation, and enable easier integration into multi-site control panels without additional verification.
Non-indicating fuses like LESRK350 reduce panel clutter and simplify installation in tight electrical rooms. Although they do not provide an on-device status indicator, the device offers high inrush protection, rugged construction, and easy integration with remote diagnostics. This design choice streamlines maintenance workflows and minimizes potential indicator-driven confusion in busy plants.
Maintenance and replacement follow standard fuse practice: stock single LESRK350 units, store as Standard packaging, and replace only after a confirmed fault or scheduled maintenance. With dimensions of 11.63 in length and 2.36 in both width and height, plus a weight of 2.36 lb, installation is straightforward in compatible fuse blocks, and end caps remain electrically isolated for safety.
