Special features
Non-indicating
High inrush current protection and a 200 kAIC interrupt rating are built into the LESRK90I, enabling safe starting and fast interruption of faults in motor circuits. This translates to lower peak fault energy, longer motor life, and reduced maintenance costs in drives, pumps, and conveyor systems. The 90 A rating supports common industrial motors while the 600 V rating ensures compatibility with standard control circuits and supply rails. The non-indicating design with electrically isolated end caps improves safety during wiring and service, minimizing misconnections in crowded panels. UL Listed and CSA Certified marks provide regulatory confidence, simplifying audits and supplier qualification for plant standards.

FAQs
The LESRK90I is ideal for motor protection in industrial drives, conveyors, and pumps where high inrush currents occur. It delivers 90 A rating at 600 V and a 200 kAIC interrupt rating, safeguarding motor windings during start-up and fault events. It is compatible with Eaton Edison Bussmann series panels and standard fuse holders for straightforward installation.
Install the fuse in a compatible Edison fuse block within a standard panel. The device features electrically isolated end caps for safe connections and a non-indicating design to simplify wiring. Dimensions are 7.88 inches in length, with 1.11 inches width and height, and a weight of 2.2 pounds, which helps planning for replacement and service access in tight spaces.
The LESRK90I carries UL Listed and CSA Certified marks, indicating adherence to recognized safety and performance standards. These certifications support regulatory acceptance in industrial facilities, streamline audits, and bolster confidence in consistent performance across maintenance cycles.
Non-indicating means the fuse does not visually signal a fault. Rely on control system feedback or remote indicators for status. This reduces wiring complexity and potential visual clutter in cabinets while still delivering reliable protection with a robust 200 kAIC interrupt rating for fault events.
