Eaton LENRK6.25 Fuse - Class RK1, 200 kAIC, 250V
Part Number: LENRK6.25
Quick Summary
Eaton LENRK6.25 fuse protects industrial motors by quickly interrupting faults while tolerating startup inrush in motor circuits. Downtime and unnecessary wear spike when protection isn’t rated for high inrush or lacks recognized UL and CSA approvals. With Class RK1 protection at 250 V and a 200 kAIC interrupt rating, it supports safety and reliability in motor circuits. Designed for OEMs and service teams, it simplifies procurement with a standard 2 in length and 10-piece packaging. In practice, you gain tighter protection margins, faster replacement, and lower total cost of ownership, especially in motor drives and conveyors. This aligns with maintenance and uptime KPIs.

Special features
Non-indicating, High in-rush current motor protection
The LENRK6.25 fuse combines robust electrical protection with practical installation advantages, delivering measurable business value. Feature: High interrupt rating of 200 kAIC reduces the risk of catastrophic motor faults, minimizing unplanned downtime and extending equipment life. Benefit: Greater line reliability translates to higher plant throughput and lower maintenance costs in continuous-duty motor applications. Application: Suitable for inrush-heavy drives in pumps and conveyors; use in standard RK1 fuse blocks to protect 6.25 A circuits without oversizing the protection. Feature: Non-indicating design reduces panel visual noise while maintaining clear replacement workflows. Benefit: Faster diagnostics and fewer misreads during routine maintenance, lowering labor time. Application: Ideal for control panels with frequent motor startups where quick fuse replacement is critical.

FAQs
LENRK6.25 fuses are designed for RK1-compatible panels and 2 in lengthy holders. Confirm the panel rating (250 V and 6.25 A per the datasheet), replace only with UL Listed/CSA Certified fuses, and ensure the fuse block is accessible for safe replacement. Verify the 10-pack packaging aligns with your stocking strategy to minimize downtime during scheduled maintenance.
LENRK6.25 features a 200 kAIC interrupt rating and 6.25 A nominal rating, enabling fast fault interruption while tolerating motor startup inrush. This combination reduces nuisance blowing on startups and safeguards motor windings, drives, and contactors. It is ideal for pumps, fans, and conveyor motors where inrush is common and reliability is critical.
LENRK6.25 adheres to the RK1 class standard and uses common Bussmann-style form factors for RK1 fuses. It plugs into standard RK1 fuse blocks found in many Eaton and third-party motor protection assemblies. Always verify alignment with panel manufacturer recommendations and use UL Listed and CSA Certified components to maintain compliance.
This fuse is UL Listed and CSA Certified, confirming compliance with recognized safety and performance standards. Certification matters for panel approvals, industrial procurement specs, and customer audits, ensuring that protection devices meet regulatory requirements and support safe operation in motor control circuits at 250 V ratings.
The LENRK6.25 provides durable protection with a high interrupt rating and a compact footprint, reducing downtime and replacement complexity. Packaged in 10-piece sets, it lowers procurement friction, while UL/CSA certifications simplify compliance processes. Over time, this translates to lower maintenance labor costs and improved uptime for critical motor-driven equipment.
