Non-indicating
High inrush current protection delivers robust startup safeguarding for motors in conveyors, pumps, and HVAC drives. The business impact is reduced nuisance trips and minimized downtime during plant start-ups, accelerating commissioning and improving overall equipment availability. This is especially beneficial in drive-enabled lines where reliable motor protection directly correlates with throughput and energy efficiency. The 200 kAIC interrupt rating at 600 V ensures fast fault interruption, protecting wiring and control gear from severe fault currents and lowering repair costs after faults in motor feeders and MCCs. Non-indicating design reduces maintenance overhead and visual chatter, while enabling integration with remote status monitoring via protection relays or industrial I/O networks. The solution pairs well with standard Eaton Edison LESRK family modules and common fuse blocks, offering straightforward installation and consistent protection across industrial facilities. The compact 5 in length and standard packaging simplify retrofit projects, field replacements, and inventory management. Industry context favors these fuses for motor-driven equipment in manufacturing, packaging, and process industries where uptime and safety are paramount. OEMs benefit from predictable performance, simplified sourcing, and clear compliance alignment with UL and CSA certifications.

FAQs
Install the LESRK6I in a compatible fuse block rated for 600 V and 6 A. Use standard wiring practices, ensure proper clearance, and secure with approved fuse holders. Since it is non-indicating, verify motor protection status via a separate relay or monitoring device for reliable fault indication and easier maintenance.
This fuse is suitable for motor protection in drives, MCCs, conveyors, pumps, compressors, and HVAC systems where high inrush protection is required. Its 200 kAIC interrupt rating at 600 V makes it appropriate for high-current fault scenarios found in industrial plant equipment.
The LESRK6I is UL Listed and CSA Certified, reflecting compliance with common North American electrical protection standards. It is designed for 600 V service and 200 kAIC fault interruption, aligning with typical motor protection requirements in industrial facilities.
Non-indicating fuses do not provide a visual status indicator; you should pair them with a separate protection relay or remote monitor. This reduces nuisance indicators in the field and allows centralized status monitoring, which can lower maintenance labor and improve fault diagnostics in panel assemblies.
Yes. The LESRK6I is part of Eaton's Edison Bussmann family and uses standard packaging suitable for common fuse blocks in motor control cabinets. Its 5 in length and 0.81 in width/height support straightforward retrofits and upgrades, with straightforward sourcing and consistent protection across multiple drive configurations.
