Special features
Indicating, High in-rush current motor protection
Feature: High interrupt rating of 200 kAIC provides robust fault interruption for large motor inrush events. Business Impact: Reduces downstream damage and unplanned downtime, enabling higher overall equipment effectiveness in production lines. Application: Suitable for heavy-duty industrial drives in conveyors, pumps, and fans where reliable fault clearing is critical. Feature: 300 A amperage rating supports motor protection during startup surges without nuisance nuisance trips that stall lines. Business Impact: Improves process continuity and reduces maintenance costs by limiting unnecessary stops. Application: Ideal for high-inertia motors in packaging or material handling. Feature: Electrically isolated end caps enhance safety during maintenance and service operations. Business Impact: Improves technician safety and minimizes accidental shorts in crowded panel assemblies. Application: Retrofit into standard Edison LENRK fuse holders and common fuse blocks. Feature: Non-indicating fuse (no external indicator required) simplifies panel visibility and reduces false alarms when used with external status monitoring. Business Impact: Streamlines PLC/HMI integration and lowers commissioning time. Application: Preferred in automation architectures where indicators are provided by separate instrumentation. Feature: Certifications CSA Certified and UL Listed. Business Impact: Ensures regulatory compliance and supplier credibility, easing procurement audits. Application: Required for regulated facilities and safety-critical motor control installations. Feature: Packaging Type Standard and Quantity 1. Business Impact: Predictable, straightforward stocking and replacement in maintenance inventories. Application: Fits typical maintenance cycles in manufacturing environments.

FAQs
Install LENRK300I in a compatible fuse holder rated for up to 300 A and appropriate voltage (250 Vac or 125 Vdc). Ensure the fuse is the correct LENRK300I catalog number, verify the end caps are electrically isolated, and follow the Eaton LENRK datasheet for torque and connection procedures. The unit is sold in standard packaging (1 per pack) for straightforward stocking.
LENRK300I is rated for 300 A with a 200 kAIC interrupt capacity. It supports 250 Vac and 125 Vdc operation, making it suitable for both AC and DC motor circuits in industrial equipment. The fuse is non-indicating and CSA Certified UL Listed, providing regulatory assurance for safety-critical applications.
Yes. LENRK300I is specifically designed for high inrush current motor protection, allowing motors to start without nuisance tripping while still safeguarding against faults and short circuits in demanding drive environments.
LENRK300I carries CSA Certification and UL Listing. These certifications support regulatory compliance, quality assurance, and reliability in safety-critical motor protection applications.
By delivering reliable fault interruption with a high 200 kAIC rating and robust inrush handling, LENRK300I minimizes unplanned downtime and panel-maintenance costs. Its non-indicating design simplifies status integration, while CSA UL certification reduces procurement risk, contributing to a favorable total cost of ownership over motor drives and the associated production lines.
