Eaton LENRK450I Edison Fuse - UL Listed 200 kAIC

LENRK450I delivers high inrush motor protection for demanding drives, reducing nuisance trips during startup. The business impact is smoother commissioning and fewer unplanned shutdowns, translating to higher line efficiency in conveyors, pumps, and fans. This fuse is designed for industrial motor circuits that encounter elevated inrush currents and harsh operating conditions, aligning with motor protection and electrical protection requirements. With a 450 A amperage rating and a 200 kAIC interrupt rating, LENRK450I safely clears faults without exposing upstream devices to dangerous fault currents. This improves safety, protects contactors and wiring, and lowers spare-part costs by reducing resistor and coil damage. The device supports 250 Vac and 125 Vdc systems, offering flexible compatibility with both legacy controls and modern drives. Electrically isolated end caps enhance installation safety and serviceability by minimizing arcing risks during wiring and replacement. The 70/30 brass end caps further improve conduction reliability and torque retention in panel boards and motor feeders. Together, these features streamline installation and reduce maintenance time in harsh industrial environments. The non-indicating fuse design simplifies panel aesthetics and reduces false readouts, while still permitting control-system monitoring to confirm operation. Standard packaging supports straightforward stocking and procurement workflows, enabling faster project ramp-up and easier re-ordering for maintenance spares. For engineers, these considerations translate into lower total cost of ownership without compromising protection. Certified for safety, the LENRK450I carries CSA certification and UL listing, reinforcing compliance across North American electrical standards. In regulated facilities, this helps satisfy audit requirements while ensuring reliable motor protection in critical applications such as process lines and material handling.
