FAQs
Install LENRK1.25 in standard Edison fuse blocks, ensuring the 2 inch depth and 0.56 inch width fit your enclosure. Use the standard packaging quantity of ten fuses per order and the 70/30 brass end caps for reliable contact. Verify 250 V rating and 1.25 A amperage before energizing. Follow lockout/tagout procedures.
LENRK1.25 is engineered to endure motor startup surges with a 200 kAIC interrupt rating and 250 V rating. This combination limits fault energy while allowing normal inrush behavior, minimizing nuisance trips. The non-indicating design reduces panel maintenance, and the compact 2 in length simplifies retrofits in crowded motor control centers.
Yes. LENRK1.25 carries UL Listed and CSA Certified marks, confirming compliance with North American electrical safety standards. This certification supports warranty, insurance, and regulatory acceptance for control panels and motor-start circuits. Always verify the certificate scope in the Eaton specification sheet to ensure alignment with your regional requirements.
LENRK1.25 is well-suited for motor protection in industrial drives, conveyors, pumps, and fans where consistent startup protection is needed. Its compact size and high interrupt rating make it a practical choice for OEM panels, retrofit projects, and serviceable motor control centers in manufacturing and packaging lines.
LENRK1.25 reduces maintenance needs with its non-indicating design, while the 70/30 brass end caps enhance contact reliability and lifespan. A higher interrupt rating minimizes nuisance trips and component damage, lowering downtime and repair costs. Space-efficient packaging and a 10-fuse bundle simplify procurement, inventory control, and long-term total cost of ownership.
