The LENRK45I fuse is engineered for high inrush motor protection in industrial drives. By tolerating brief startup surges without compromising protective clearances, it minimizes unplanned downtime and extends motor life in fans, pumps, conveyors, and packaging lines. This alignment with common OEM motor controls helps facilities maintain consistent throughput even during peak demand. The compact 3 in body and 0.81 in cross-section simplify panel layouts and reduce enclosure fill. Electrical performance is balanced for reliability: 45 A continuous rating, 250 V operating voltage, and a 200 kAIC interrupt rating. The fuse clears faults rapidly, protecting cables and power electronics while keeping downstream devices energized. In practice, operators see fewer nuisance trips and more stable speed control in variable-load applications like fans and pumps. Compatibility and installation are streamlined by standard packaging and robust end caps. The 70/30 brass end caps improve current sharing and heat dissipation in harsh environments, while the standard packaging of ten fuses per box supports predictable spares planning. When used in Edison Bussmann style holders, replacement is straightforward and downtime is minimized. Non-indicating design reduces false alarms in dense control panels, which helps remote diagnostics and reduces maintenance overhead. The fuse's mechanical robustness and UL CSA certifications provide confidence for retrofit projects and new builds alike. Design resilience supports long service life and predictable maintenance budgets, with compatibility for standard control circuits and motor starters. In teams aiming for uptime, LENRK45I offers a clear path to improved reliability and safer operations in manufacturing environments.

FAQs
To install LENRK45I, first ensure the fuse holder is compatible with Edison Bussmann style devices. Align the 3 inch body with the holder’s cavity, insert the fuse firmly, and secure any end caps. Verify electrical connections are clean and tightened to spec. Replace in sets of ten to maintain spare availability and consistent protection across panels.
LENRK45I provides a 45 A amperage rating, operates at 250 V, and offers a 200 kAIC interrupt rating. These values enable reliable protection for motor starter circuits and drives against overloads and short-circuit faults while keeping system voltage within safe operating limits.
This fuse is ideal for motor protection in drives, conveyors, pumps, fans, and other heavy-duty equipment with high inrush characteristics. Its UL Listed and CSA Certified status supports use in compliant control panels and retrofit projects, ensuring consistent performance in automated manufacturing lines without nuisance tripping during startup surges.
LENRK45I carries UL Listed and CSA Certified approvals, signaling compliance with recognized safety standards for electrical protection. These certifications support regulatory adherence, facilitate audits, and give engineers confidence when integrating the fuse into North American electrical protection schemes in new builds or retrofits.
LENRK45I provides measurable uptime advantages by reducing nuisance trips during motor startups, lowering unplanned downtime. Its durable construction, standard packaging, and compatibility with existing holders streamline maintenance planning and spare management, delivering lower total cost of ownership in mid-to-large industrial facilities.
