The LENRK25 fuse offers a 25 A amperage rating with a 200 kAIC interrupt capability at 250 V, which translates to robust motor protection against high inrush and short-circuit events in demanding industrial environments. This feature reduces unplanned downtime and protects costly equipment, improving overall line reliability and uptime. The Class RK1, non-indicating design provides straightforward integration into standard Edison fuse holders and RK1 fuse blocks, enabling predictable protection without requiring specialized monitoring. The 70/30 brass end caps enhance contact integrity and reduce resistance at connection points, delivering lower thermal stress and longer service life in panel installations. Packaging of 10 units per standard pack supports efficient stocking, procurement, and replacement workflows for maintenance teams. The combination of UL Listed and CSA Certified confirms regulatory compliance and facilitates procurement approvals across regulated facilities. Compatibility with the Eaton Edison fuse family streamlines inventory and installation in motor control centers and industrial controls, mitigating compatibility concerns and accelerating project timelines. This fuse is well-suited for applications where consistent motor protection is critical, including conveyors, pumps, fans, and other high-inrush loads, while offering a cost-effective, scalable solution for multi-line installations.

FAQs
LENRK25 is designed for standard Edison fuse holders and RK1 fuse blocks. To install, ensure the fuse holder is rated for 25 A and 250 V, visually verify the fuse length and end-cap compatibility (70/30 brass end caps), then insert firmly into the holder to ensure solid contact. Use proper PPE and de-energize circuits before replacement. Maintain a spare stock of LENRK25 units (10 per standard pack) for quick field replacements to minimize downtime.
LENRK25 is rated for 25 A with an interrupt rating of 200 kAIC and a voltage rating of 250 V. These ratings indicate suitability for motor protection in circuits with high inrush currents while delivering robust short-circuit handling. The 200 kAIC interrupt rating helps minimize fault energy transfer to downstream components, supporting longer equipment life in demanding industrial environments.
Yes. The LENRK25 fuse is designed for high inrush motor protection, combining a 25 A rating with a 200 kAIC interrupt rating and a 250 V operating voltage. Its RK1 class designation ensures selective coordination with other protective devices in motor circuits, reducing nuisance trips while preserving motor startup performance in pumps, fans, conveyors, and similar equipment.
LENRK25 carries UL Listed and CSA Certified markings, which verify compliance with recognized electrical safety standards. These certifications aid procurement and installation in regulated industries, facilitate inspector acceptance, and help ensure that motor protection devices meet essential safety and performance criteria for industrial control panels and equipment.
LENRK25 fuses reduce maintenance by offering predictable, long-term protection with minimal field adjustments due to their non-indicating design. The 70/30 brass end caps improve connection reliability, lowering contact resistance and wear. The 25 A/250 V ratings support durable protection for common motor loads, contributing to lower downtime, fewer fuse-related failures, and improved total cost of ownership over the device’s lifecycle.
