Special features
70/30 brass end cap
Non-indicating construction with 70/30 brass end caps improves connection reliability and minimizes contact resistance, delivering lasting performance in motor feeder circuits and drive enclosures. This translates to fewer field faults and less maintenance overhead, especially in environments with vibration or frequent cycling. In application terms, the LENRK30 supports high inrush current scenarios typical of conveyor systems and pump drives, reducing nuisance trips while preserving protective selectivity. The 30 A, 250 V rating paired with a 200 kAIC interrupt capability provides robust short-circuit protection for medium-to-large motors, directly contributing to reduced arc energy exposure and faster fault clearing in panel boards. Its Class RK1 designation ensures compatible coordination with standard fusing schemes, enabling straightforward retrofits in existing Eaton Edison installations. The device’s compact 2 in length and 0.56 in width/height profile simplifies panel integration in tight switchgear spaces, easing routing and installation time. Packaging is standard, with ten units per pack, supporting consistent stocking and streamlined procurement. Certifications are clearly documented (UL Listed, CSA Certified), reinforcing compliance for regulated environments. The non-indicating design reduces visual wear in crowded control cabinets, while the overall lightweight form factor minimizes handling risk during installation. In summary, LENRK30 offers a proven balance of protection, compatibility, and ease of use that translates into measurable uptime and lower total cost of ownership for motor control applications.

FAQs
LENRK30 is designed for straightforward panel installation in standard RK1 fuse blocks. It has a compact 2 in body length and 0.56 in width/height, which fits most Eaton Edison assemblies. Ensure proper alignment of the brass end caps with bus contacts to minimize resistance, and verify the panel is rated to 250 V and 30 A. Proper torque on connections helps prevent heat buildup during high inrush conditions.
LENRK30 is a non-indicating fuse rated for 30 A and 250 V with a 200 kAIC interrupt rating, making it well-suited for motors with significant inrush currents. The Class RK1 design supports coordinated protection with standard motor circuits, while UL Listed and CSA Certified marks assure safety and compliance across installations. This combination enables reliable fault clearance without nuisance trips in demanding motor drives.
Yes. LENRK30 is specified for AC motor protection in industrial panels and drive networks. Its 250 V rating and 200 kAIC interrupt capability are aligned with typical AC motor protection needs, while the RK1 class provides predictable coordination with other protective devices. The non-indicating design reduces visual wear in dense control cabinets, aiding quick inspection and maintenance.
LENRK30 carries UL Listed and CSA Certified marks, signaling compliance with recognized safety and performance standards. These certifications help satisfy procurement policies, insurance requirements, and electrical codes in many jurisdictions. By selecting a fuse with these certifications, teams can streamline supplier qualification and expedite approvals for regulated facilities.
LENRK30 offers predictable protection for high inrush motors, reducing unplanned downtime from nuisance trips and short circuits. Its robust 200 kAIC interrupt rating minimizes arc energy and facilitates faster fault clearing, which lowers maintenance costs and extends motor life. The standard ten-pack aids inventory management, reducing stockouts and procurement lead times in production environments.
