Eaton KTN-R-15 Fuse - Class RK1 Current-Limiting
Part Number: KTN-R-15
Quick Summary
The Eaton KTN-R-15 fuse provides fast-acting, current-limiting protection for industrial control circuits. In many panels, undersized protection leads to nuisance trips or extended downtime during faults; this device helps minimize those events with precise ratings. This model is a 15 A, 250 V Class RK1 fuse featuring a rejection-style ferrule end and 70/30 brass end caps for robust field installation. Data for this SKU lists Compliances as Not Applicable; however, confirm CE/UL or region-specific certifications as required by your safety and procurement standards. Ideal for control panels, motor starters, and automation cabinets, the KTN-R-15 integrates smoothly with Bussmann series components to streamline spare part kits and maintenance cycles.

FAQs
Install the KTN-R-15 by seating it between ferrule-end conductors that match the 2 in length and 0.56 in diameter. Ensure proper alignment of the ferrule ends, verify a secure crimp or solder-free ferrule connection, and confirm the 15 A rating matches the circuit requirements. Use appropriate safety procedures and confirm the end caps are fully seated to prevent arcing.
The KTN-R-15 is rated for 15 A at 250 V with a 200 kA interrupting rating at 250 VAC. It is a fast-acting, current-limiting Class RK1 fuse. Use it to protect industrial control circuits, PLC panels, and motor-starting circuits where high fault currents could cause damage and where rapid interruption is beneficial.
Yes. The KTN-R-15 is part of Eaton Bussmann’s Bussmann series and adheres to RK1 class design. It uses ferrule-end terminations and is designed for seamless integration with standard RK1 panel installations, improving repair times and stocking efficiency in facilities that already use Bussmann products.
The provided product data lists Compliances as Not Applicable, so verify regional regulatory requirements (such as CE/UL/CSA) with your purchasing guidelines. For RoHS and related disclosures, use the RoHS Search Tool provided by Eaton to confirm any applicable restrictions in your region.
By delivering fast fault interruption and high interrupting capacity (200 kA), the KTN-R-15 reduces nuisance trips and equipment damage, increasing line uptime and reducing unplanned downtime.
