Eaton LENRK.3 Fuse - UL Listed, 200 kAIC
Part Number: LENRK.3
Quick Summary
LENRK.3 fuse protects motors with high in-rush currents in industrial drives. Engineers struggle with nuisance trips and undersized protection that slow production; LENRK.3 minimizes both by tolerating brief surges while still safeguarding cabling and controls. UL Listed and CSA Certified, with a 250 V rating and 0.3 A amperage, it provides compliant, reliable protection for small-motor circuits. Designed for standard packaging and easy installation, LENRK.3 helps streamline procurement, improve uptime, and reduce spare-parts inventory in electrical protection and motor-control panels.

Special features
With minimal time delay
Feature → Business Impact → Application: Non-indicating design reduces panel indicators and potential false alarms, delivering cleaner control panels and easier diagnostics in motor-control cabinets. This supports reduced maintenance time and faster troubleshooting during commissioning or upgrade projects. Application: small-motor protection in industrial drives where visibility of fuse status is managed elsewhere yet reliable protection is critical. Feature → Business Impact → Application: High interrupt rating of 200 kAIC provides rugged fault tolerance for motor circuits facing short-circuit events or high inrush, lowering risk of wiring damage and cascading equipment failures. Application: drives and starters in departmental automation lines that require robust fault clearing. Feature → Business Impact → Application: 0.3 A amperage rating matches common control-circuit motors, enabling precise protection without nuisance tripping, improving energy efficiency and reducing spare parts inventory. Application: control panels and motor control centers in manufacturing floors. Feature → Business Impact → Application: 250 V voltage rating ensures compatibility with standard industrial power distributions, enabling straightforward integration into existing panels and schematics. Application: electrical protection in machine bays and line-start applications. Feature → Business Impact → Application: With minimal time delay, LENRK.3 balances protection with motor startup dynamics, supporting reliable start-up sequences and minimizing lost production time. Application: conveyor systems, pump skids, and material-handling equipment in process industries.

FAQs
LENRK.3 fuses are designed for standard Edison fuse holders used in motor control and protection panels. To install, ensure power is isolated, confirm the 0.3 A rating matches the motor circuit, insert the fuse into the holder securely, and re-energize the circuit after verifying proper latching in the fuse block. Always follow OEM panel guidelines and lockout procedures.
LENRK.3 is suited for small motor control circuits and drives with brief startup surges. It provides protection against short circuits while tolerating inrush, making it ideal for control panels, starters, and equipment where compact protection is required without sacrificing reliability.
Key ratings include an amperage of 0.3 A, interrupt rating of 200 kAIC, and a voltage rating of 250 V. Packaging is standard with a catalog number LENRK.3. The fuse is UL Listed and CSA Certified, ensuring regulatory compliance for industrial applications.
Yes. LENRK.3 carries UL Listed and CSA Certified marks, indicating compliance with recognized safety standards. This supports regulatory acceptance in diverse markets and reduces the time needed for qualification testing in motor-protection applications.
LENRK.3’s non-indicating design minimizes unnecessary indicator checks, while its robust 200 kAIC interrupt rating reduces fault-related downtime. The 0.3 A rating fits small-motor protected circuits, lowering spare-part costs and improving mean time between failures (MTBF) in automation lines.
