Special features
Non-indicating, High in-rush current motor protection
Non-indicating design with electrically isolated end caps simplifies wiring in tight control panels and reduces field wiring faults. The LENRK80’s end-cap isolation helps technicians troubleshoot without disturbing the circuit, and its compact 5.88 in length fits common panel cutouts. Business impact includes faster installation, fewer nuisance indicators, and lower risk of mis-wiring during maintenance. This makes it ideal for motor starter assemblies and general-purpose motor protection in light to medium duty applications. High inrush current protection is purpose-built for electric motors, allowing safe starting without premature tripping. The LENRK80 handles brief surge currents while maintaining reliable shutdown during faults, reducing unscheduled downtime and extending motor life. In conveyors, pumps, and fans, this targeted protection translates to improved line efficiency and predictable maintenance planning. Installation compatibility with standard Eaton Edison fuse blocks supports quick upgrades without redesigns. Class RK1 classification supports standard motor-fusing practices and aligns with global electrical codes. The LENRK80 delivers robust protection with an 80 A rating and a 200 kAIC interrupt rating, providing fast clearing for short-circuit events. This combination minimizes arc energy and equipment damage while preserving service continuity for HVACs, pumps, and machine tools. Its RoHS compliance further simplifies sustainability reporting and regulator-friendly installations. Compliance-first design means easier global deployment. CSA Certified and UL Listed marks provide clear safety validation, while RoHS adherence reduces hazardous substances in end products. The LENRK80 is suitable for panel builders and OEMs seeking confidence in regulatory compliance across North America and beyond. With standard packaging of five fuses per order, procurement teams can optimize stocking levels and streamline reorder cycles during plant maintenance. Voltage versatility and compact footprint. Rated for 250 Vac and 125 Vdc, LENRK80 fits in mixed-voltage control circuits and mixed motor drives, reducing part variety. The 5-piece supply supports timely replacements and spare-part consistency in maintenance windows. Installation notes emphasize using properly rated fuse holders and torque specifications to prevent end-cap loosening during vibration, ensuring long service life in demanding environments.
