Special features
Non-indicating, High in-rush current motor protection
Non-indicating design reduces panel clutter and eliminates nuisance indicators during routine diagnostics. This translates to faster fault confirmation and less operator noise in high-output environments. Compatible with standard Edison fuse blocks, it simplifies stocking and accelerated replacement in critical lines. High inrush current motor protection with a 2.25 A rating and 200 kAIC interrupt rating safeguards motors during startup surges without sacrificing line continuity. This makes it ideal for conveyors, pumps, and machine tools with short startup transients, delivering improved uptime and longer motor life. 600 V voltage rating with UL Listed and CSA Certified compliance ensures alignment with global electrical safety standards, simplifying audits and supplier qualification for multinational facilities. The RK1 class is well understood in industrial motor protection, enabling consistent performance across equipment types. Compact dimensions—5 inches in length with a 0.81 inch by 0.81 inch footprint and a weight of 1.6 lb—facilitate installation in confined enclosures and reduce panel modification time. Standard packaging and a non-indicating feature support straightforward replacements and maintenance planning. Compatibility with the Eaton Edison fuse family enables quick upgrades, streamlined procurement, and a unified protection strategy across motor control applications.

FAQs
The LESRK2.25 is designed for Eaton Edison fuse blocks and standard RK1 motor protection configurations. It fits typical Edison-style fuse holders and simplifies stocking by aligning with existing RK1 protection schemes used in motor control centers and drive systems.
Key ratings are 2.25 A amperage, 200 kAIC interrupt rating, and 600 V voltage. These specifications support reliable protection for small to mid-size motors in industrial equipment, including pumps, conveyors, and machine tools operating at standard plant voltages.
Yes. With a 200 kAIC interrupt rating and a 2.25 A rating, the fuse can withstand startup surges typical of conveyors and similar equipment, providing motor protection without unnecessary tripping under normal inrush conditions.
LESRK2.25 is UL Listed and CSA Certified, with Class RK1 protection. These certifications support regulatory compliance, aid in supplier qualification, and provide assurance of safety and performance in diverse industrial environments.
There is no warranty specified for this fuse. Plan for standard replacement using the same LESRK2.25 rating when protection is required, and take advantage of its non-indicating design to minimize panel maintenance time during inspections.
