High current protection: The LESRK8I fuse provides an 8 A rating with a 200 kAIC interrupt rating at 600 V, enabling rapid clearing of motor faults and faults on startup. This combination protects motor windings, drives, and soft starters from catastrophic damage, reducing unplanned downtime and repair costs. In practice, this means fewer unexpected plant stoppages and longer motor life in demanding environments like packaging lines and material handling. Non-indicating design: The LESRK8I uses a non-indicating fuse indicator, which simplifies panel design by avoiding multiple indicator states. The business impact is a cleaner control panel and reduced maintenance overhead because fault status is inferred from the system's protection architecture rather than a visual fuse state. This approach is particularly advantageous in dense control panels and when spare parts inventories need to be minimized. In practice, engineers rely on upstream safeguards and system-level alarms to detect fuse status, maintaining fast fault diagnosis without chasing indicator lights. Compact packaging and standard dimensions: With a length of 5 in, width 0.81 in, height 0.81 in, and a weight of 1.6 lb, the LESRK8I fits compact control boards and tight panel spaces. The standard packaging type makes replacements quick and predictable, enabling installers to stock catalog LESRK8I across facilities. The combination of compact size and a clear, catalog-numbered form reduces installation time and stocking complexity for large sites. This is especially valuable in retrofit projects where panel real estate is at a premium. Certifications and compatibility: UL Listed and CSA Certified marks demonstrate compliance with essential safety and reliability standards, easing procurement for regulated industries. The fuse is designed for 600 V systems and is compatible with Eaton Edison products and standard fuse holders, enabling seamless integration into existing protection schemes. This reduces qualification cycles for projects and supports consistent performance across machines. By choosing a trusted, certified device, maintenance teams achieve predictable protection and faster MTTR in the event of faults.

FAQs
Install LESRK8I in a compatible fuse holder or fuse block designed for Bussmann/Eaton Edison fuses. Verify catalog LESRK8I and 8 A rating match the motor nameplate. Ensure the panel is de-energized, insert the fuse fully, and secure with standard hardware. Check 600 V maximum rating and ensure compatibility with existing protection schemes and wiring clearance.
Key specs include an 8 A amperage rating, a 200 kAIC interrupt rating, and a 600 V voltage rating. Catalog number LESRK8I and UPC 782634990369 identify the device. Physical dimensions are 5 in length, 0.81 in width, and 0.81 in height, with a weight of 1.6 lb. The fuse is non-indicating and UL Listed plus CSA Certified.
Yes. The LESRK8I is designed for high inrush motor protection with a robust 200 kAIC interrupt rating at 600 V, making it suitable for conveyors, pumps, fans, and other industrial drives that experience startup surges. Its 8 A rating aligns with small to mid-size motors, providing reliable protection without nuisance trips.
The LESRK8I carries UL Listed and CSA Certified marks, indicating compliance with essential safety and reliability standards. This helps meet regulatory requirements, facilitates supplier audits, and supports procurement in regulated industries. Certifications also reassure customers about consistent performance across machines and maintenance programs.
LESRK8I fuses are standard-protection devices with no warranty and straightforward replacement. In service, monitor for fault events that trip the circuit, replace with an equivalent LESRK8I 8 A, 600 V device, and verify 200 kAIC compatibility. Keep spares stocked using the catalog and UPC to ensure fast, predictable maintenance.
