FAQs
LENRK3.2 is designed to fit within the Eaton Edison LENRK fuse family, featuring a 2 in length and compact 0.56 in footprint suitable for standard motor control panels. It provides a 3.2 A rating, 250 V operation, and a 200 kAIC interrupt capacity, ensuring seamless replacement in existing 250 V motor circuits while meeting RK1 class construction and safety certifications.
LENRK3.2 offers a 200 kAIC interrupt rating, making it suitable for motors with high startup or fault surge currents. Use it in applications where reliable interruption of peak fault currents is critical, such as in belt conveyors, pumps, and fans connected to 250 V circuits, to minimize damage and downtime during faults.
Yes, LENRK3.2 is non-indicating, which simplifies stocking and replacement in crowded panels. Maintenance considerations include periodic visual inspection and periodic replacement after fault events or aging, but the non-indicating design reduces nuisance signaling. Ensure proper replacement with an identical LENRK3.2 device to preserve listed protection performance.
LENRK3.2 carries UL Listed and CSA Certified marks, affirming compliance with global electrical safety standards. It is built to Class RK1 specifications, aligning with standard fuse types used in motor protection. These certifications simplify regulatory approvals, facilitate procurement for regulated industries, and reassure end-users about ongoing safety and compatibility in industrial environments.
Install LENRK3.2 in suitable Eaton Edison LENRK circuits within 250 V motor drives. Verify correct amperage rating (3.2 A), ensure compatible panel space (2 in length, 0.56 in width/height), and replace only with UL Listed/CSA Certified LENRK3.2 units. Proper torque, cooling, and enclosure protection are essential to maintain reliable protection during motor start-up and fault events.
