Eaton LENRK50 Fuse - RK1, UL Listed, High Inrush
Part Number: LENRK50
Quick Summary
LENRK50 fuse is a non-indicating, high in-rush motor protection device for industrial motors and feeders. Many drive systems trip during startup when protection devices aren’t tuned for inrush, causing downtime and maintenance overhead. UL Listed and CSA Certified provide regulatory confidence, while Class RK1 and a 200 kAIC interrupt rating deliver robust motor protection. With a standard 10-pack at 250 V and a compact 3 in length, LENRK50 simplifies spec consistency and stocking for OEMs and panel shops, helping installers deploy reliable protection quickly. This combination supports faster commissioning, reduced downtime, and safer electrical protection strategies across control panels and motor circuits.

Yes. LENRK50 is a 3 in long, 0.81 in wide by 0.81 in high non-indicating fuse designed for RK1 fuse blocks and Eaton Edison compatible assemblies. With standard packaging of 10 units, it integrates smoothly into typical control panels and MCCs, supporting straightforward replacement and stocking for OEMs and panel shops.
LENRK50 excels in motor circuits with high startup inrush, such as conveyors, pumps, fans, and automated machinery. Its 50 A rating and 200 kAIC interrupt capability protect against short circuits while tolerating legitimate inrush, reducing nuisance trips and motor wear during commissioning and daily operation.
LENRK50 is UL Listed and CSA Certified, with a Class RK1 designation. These certifications confirm compliance with recognized safety standards and facilitate regulatory approvals for industrial facilities, helping avoid audit findings and ensuring reliable performance in harsh environments.
LENRK50’s RK1 classification is specifically designed for motors with higher startup currents. Its 200 kAIC interrupt rating provides robust protection without premature opening during startup, balancing protective speed with inrush tolerance and minimizing downtime on motor-driven equipment.
The LENRK50 ships in standard 10-piece packs at 250 V, reducing stocking complexity and procurement effort. Its durable performance, UL Listed and CSA Certified compliance, and compatibility with common RK1 fuse blocks translate to lower maintenance costs, fewer spare-part varieties, and faster replacement in industrial control environments.
