Eaton KWN-R-6 Fuse - Class RK1, 6 A Limitron Fast Acting
Part Number: KWN-R-6
Quick Summary
Eaton KWN-R-6 fuse protects control circuits with fast acting overcurrent protection in industrial panels. In compact enclosures, selecting a dependable fuse without increasing panel complexity is a common challenge. Industry expectations for safety and reliability include CE safety standards, UL recognition for electrical components, and robust IP protection in harsher environments. The KWN-R-6 delivers a 6 A rating in a 2 in body with RK1 class fast-acting performance, and it remains non-indicating to keep panel aesthetics clean. This combination supports easy stocking, faster replacements, and predictable performance, reducing downtime and spare-parts costs. By aligning with Bussmann’s Limitron family, it also offers familiar form factors for quick integration into existing electrical protection schemes.

Eaton Specification Sheet - KWN-R-6
6 A amperage rating with RK1 class fast-acting behavior provides reliable overload and short-circuit protection for sensitive automation circuits, reducing nuisance trips and downtime in control panels. This feature translates to improved machine uptime and predictable protection during rapid fault events, especially in distributed automation networks where fast response is critical. The Limitron fast-acting design accelerates interruption of fault currents, minimizing energy let-through and protecting downstream electronics such as PLCs and sensors. In practical terms, engineers gain better fault discrimination and easier fault isolation during maintenance, improving diagnostic efficiency and reducing repair costs. The non-indicating indicator keeps panel aesthetics clean while simplifying replacement logistics in high-density installations. The compact 2 in length and 0.56 in width/height enable easier integration in crowded enclosures and standard Bussmann fuse blocks, supporting streamlined procurement via the Eaton catalog and datasheets. Standard packaging and a readable UPC simplify stocking and reordering in procurement systems.

FAQs
The KWN-R-6 is a compact 2 inch long, 0.56 x 0.56 inch fuse designed for standard Bussmann limitron fuse blocks and RK1 protection holders commonly used in control panels. It pairs with typical mechanical fuse blocks and replacement parts, enabling quick swaps during maintenance. Ensure the holder accommodates a non-indicating RK1 cartridge and that the mounting spacing matches your enclosure design to maintain clearance and wiring integrity.
KWN-R-6 is a 6 A amperage rating fuse, classified as Class RK1, and is a Limitron fast-acting design. This combination provides rapid interruption of short-circuit faults while allowing normal operating currents to pass, protecting sensitive automation components. Its non-indicating feature means no visible trip indicator, which can simplify panel aesthetics in environments with constrained visual monitoring.
Yes, the KWN-R-6 is well-suited for control panels and automation systems requiring compact, reliable short-circuit protection. The 2 in body fits densely populated enclosures, and the RK1 fast-acting characteristic supports fast fault clearing in PLC inputs, sensors, and small drives. Its non-indicating style is advantageous where indicators are not required or are managed elsewhere in the system.
Verify certifications directly from the manufacturer documentation, such as UL recognition, CE safety compliance, and any IP ratings relevant to your environment. While the KWN-R-6 specification highlights RK1 class and Limitron fast-acting performance, certification marks depend on the market and application. Always consult Eaton’s datasheets and catalogs, like the KWN-R-6 spec sheet, to confirm current regulatory markings for your region.
Using the KWN-R-6 can lower maintenance costs through reduced downtime due to reliable fast-acting protection and easy replacement with standard Bussmann parts. The compact form factor simplifies stocking in limited spaces, and the availability of official catalogs and datasheets improves procurement efficiency. Overall, you gain faster fault isolation, predictable performance, and streamlined replacement processes with long-term cost savings.
