Eaton KWN-R-10 Fuse - Class RK1, 10 A, Ferrule Design
Part Number: KWN-R-10
Quick Summary
KWN-R-10 fuse from Eaton Bussmann protects control circuits in panels and machines by providing reliable overcurrent protection. This helps reduce nuisance trips and compatibility issues that disrupt production and raise maintenance costs. Note: Certifications such as SIL, CE, or IP ratings are not specified in the product data, but the fuse is built as a Class RK1 device with a ferrule design for robust field installation. By standardizing on the Bussmann-series line, maintenance teams gain predictable performance, easier sourcing, and a streamlined spare-parts strategy. This approach supports efficiency goals and total-cost-of-ownership improvements in automation environments where quick interchangeability and minimized downtime matter.

FAQs
The KWN-R-10 is a 2 in long, 0.56 in wide Class RK1 fuse designed for ferrule-terminal assemblies. It fits standard Bussmann-series enclosures and RK1-compatible holders used in control panels. When installing, ensure proper ferrule termination, correct current rating (10 A), and appropriate panel clearance. This simplifies upgrades and replacements in existing automation racks.
The KWN-R-10 provides a 10 A amperage rating and belongs to Class RK1, with a non-indicating fuse indicator. It uses a ferrule design for secure terminations and standard packaging suitable for panel-mounted protection. Verify system voltage, interruption rating, and short-circuit current to confirm suitability for your specific control circuit and safeguarding requirements.
This fuse is well-suited for electrical protection in automation panels, machine control circuits, and small industrial equipment. Its compact 2 in length and ferrule-term compatibility make it ideal for retrofit projects in existing control panels and for new installations where RK1-class protection and standard Bussmann-series parts are preferred for procurement efficiency.
The provided data does not list specific certifications such as SIL, CE, or IP-rated compliance for the KWN-R-10. It is identified as a Class RK1 fuse with non-indicating features and Ferrule design. Users should verify regulatory requirements with their end-user specifications or Eaton's technical support for any project-specific certification needs.
Using the KWN-R-10 supports ROI through standardized sourcing from the Eaton Bussmann family, predictable performance in control circuits, and a ferrule-design termination that reduces field wiring issues. Its compact footprint and non-indicating status lower maintenance complexity, while the 10 A rating provides targeted protection, reducing downtime and extending panel reliability in automation environments.
