High-current protection → Business Impact → Application: The LENRK350I provides a 350 A amperage rating and a 200 kAIC interrupt capacity, enabling fast clearing of motor fault currents and minimizing damage to drives and wiring. In industrial facilities, this translates to reduced unplanned downtime and extended motor life in conveyor lines, pumps, and fans. This rugged motor protection is ideal for installation in motor control centers and panel boards where high inrush events occur. Indirect savings include lower repair costs and improved energy efficiency during fault events. Compatibility with the Edison LENRK line ensures a familiar footprint and streamlined procurement for maintenance teams. PLCs and MCCs benefit from fewer nuisance trips thanks to robust short-circuit protection and clear rating data.

FAQs
LENRK350I is designed for industrial motor protection in drives and conveyor systems. With a 350 A rating and 200 kAIC interrupt capability, it protects motors from inrush transients and short-circuit events. Its compatibility with Edison LENRK panels makes it ideal for MCCs and control cabinets in manufacturing environments, where reliable protection minimizes downtime and equipment wear.
Install LENRK350I as a standard fuse within Edison LENRK enclosures. The device uses a standard packaging footprint and the 70/30 brass end caps facilitate robust, low-resistance connections. With a compact 8.63 in length and 2.36 in square profile, it fits typical protection blocks. Ensure proper alignment with electrically isolated end caps and confirm the 1-unit quantity per protection circuit for consistent protection.
Yes. LENRK350I is CSA Certified and UL Listed, providing recognized safety and compliance for electrical protection devices. This certification helps satisfy regulatory procurement requirements and supports risk management during audits. The combination of high interrupt rating (200 kAIC) and voltage ratings (250 Vac / 125 Vdc) further ensures alignment with typical industrial motor control standards.
Key ratings include a 350 A amperage rating, 200 kAIC interrupt rating, and voltage ratings of 250 Vac and 125 Vdc. The fuse is non-indicating, with standard packaging and 1 unit per pack. These specifications enable effective protection for high-inrush motors and ensure compatibility with common control circuits and Edison LENRK assemblies.
Using LENRK350I can reduce downtime from motor faults by quickly interrupting fault currents, protecting motor windings and drives. The CSA UL certifications simplify compliance, while the robust 200 kAIC rating supports reliable operation under short-circuit conditions. With straightforward sourcing and installation, maintenance costs decrease and asset uptime improves, delivering a favorable total cost of ownership in manufacturing environments.
