LENRK2.5 fuse features a compact 2 inch length and a square 0.56 inch footprint, enabling denser control cabinets and easier wiring in motor control centers. The small form factor does not compromise protection; it is rated for 2.5 A, 250 V and delivers 200 kAIC interrupt capacity to handle severe faults common in industrial drives. This combination supports faster installations and reduced panel size, which translates to lower material costs and shorter commissioning times. In retrofit projects, the compact fuse simplifies space planning and minimizes changes to adjacent components, improving overall project risk posture. Non-indicating design reduces indicator maintenance and eliminates nuisance trips caused by misread status. The 70/30 brass end caps provide low-resistance, high-strength contact surfaces that maintain performance after repeated switching and high inrush surges. The LENRK2.5’s electrical ratings—2.5 A, 250 V, 200 kAIC—make it reliable for motor loads and high-energy faults, while compatibility with RK1 blocks and Eaton Edison components ensures a cohesive protection strategy. The standard packaging (10 per pack) supports efficient stocking and field replacement, and its 2 inch length aligns with common panel slot sizes. Industry practitioners benefit from reduced spare parts variety and predictable lead times, contributing to lower maintenance costs and faster downtime recovery. From a design perspective, the fuse’s non-indicating feature minimizes heat and panel clutter, and the 70/30 brass end caps enhance contact reliability across thermal cycles, delivering consistent protection over the equipment lifecycle.

FAQs
LENRK2.5 is designed to fit standard RK1 fuse blocks used in motor control panels. It follows the Eaton Edison LENRK series dimensions and uses 70/30 brass end caps for reliable contact. Its 2 in length and 0.56 in width support straightforward retrofits and stock compatibility with other LENRK fuses, reducing design variation and procurement complexity.
LENRK2.5 provides 2.5 A protection at 250 V with a 200 kAIC interrupt rating. It is non-indicating and UL Listed, CSA Certified, with Class RK1 protection. These specs ensure reliable short-circuit protection for motor loads and high-energy faults while meeting common electrical codes and drive applications.
Yes. LENRK2.5 is designed to handle high inrush conditions typical of VFD-driven motors and conveyors. Its 200 kAIC interrupt rating provides strong fault energy handling, while the 2.5 A rating at 250 V suits low-to-medium current motor protection in industrial drives, helping minimize nuisance trips and downtime.
Yes. The LENRK2.5 fuse is UL Listed and CSA Certified, aligning with electrical code requirements for panel boards and motor starters. These certifications support safe installation, standardization across equipment, and streamlined approval processes during design reviews.
Standardizing on LENRK2.5 reduces spare parts variety and simplifies procurement with a familiar 10-pack packaging. The non-indicating design lowers maintenance time, while robust end caps and reliable protection reduce unplanned downtime. Over multiple lines, this can translate to lower inventory costs, faster repairs, and a shorter return on investment for motor-protection upgrades.
