Eaton KWN-R-15 Fuse - Class RK1, Non-indicating
Part Number: KWN-R-15
Quick Summary
The Eaton KWN-R-15 fuse is a protective device designed to interrupt fault currents in industrial control panel circuits. Nuisance trips, difficult sourcing, and downtime slow productivity and inflate maintenance costs. Data lists Class RK1 and non-indicating status, but CE, SIL, and IP certifications are not shown; confirm regional compliance before deployment. As part of the Bussmann series, it fits standard DIN rail installations and supports quick field replacement, improving overall reliability for panel builders and maintenance teams.

Eaton Specification Sheet - KWN-R-15
The 15 A rating paired with Class RK1 provides precise overcurrent protection for industrial controls, reducing the risk of equipment damage and costly downtime while supporting compliant panel design. The knife blade feature offers robust electrical contact and straightforward replacement during service, boosting uptime in high-demand environments and enabling faster changeouts in manufacturing lines. Its compact 2 in length and 0.56 in width/height footprint allows easy integration into space-constrained DIN rail panels, delivering higher component density and cleaner panel layouts with less wiring clutter. Non-indicating status minimizes visual indicators in control cabinets, reducing panel wear and simplifying lighting requirements while maintaining reliable fault indication in upstream protection schemes. Traceability is enhanced by the UPC 051712407557 and catalog reference KWN-R-15, aligning with the Bussmann series for streamlined procurement and consistent stocking. Weighing 0.4 lb and packaged standard, the unit supports straightforward handling, shipping, and replacement in service trains and field installs.

FAQs
The KWN-R-15 is designed for standard Bussmann series fuse holders and DIN rail-mounted panels. Verify that the holder accommodates Class RK1 fuses and the 2 inch length with a 0.56 inch width. When installing, align the knife blade contacts for a secure, low-resistance connection and ensure the circuit is de-energized prior to replacement to prevent electrical shock.
A 15 A rating indicates the fuse will interrupt current above 15 A to protect wiring and components from overcurrent. Class RK1 denotes a general-purpose fuse class with standardized dimensions and characteristics for fast-acting protection. This combination is suitable for protecting small to mid-range control circuits in industrial equipment while supporting predictable clearing times.
Yes, the KWN-R-15 is intended for DIN rail installations in industrial control panels. Its compact 2 in length and RK1 classification facilitate integration into tight panel spaces and standard Bussmann series ecosystems, enabling reliable protection for motor starters, relays, and control circuitry without extensive rework.
The provided data lists Class RK1 and non-indicating features but does not show CE, SIL, or IP certifications. Users should verify regional regulatory requirements with the procurement team or Eaton’s specifications sheet to ensure compliance for their specific market and application.
The KWN-R-15 provides predictable trip performance at a known current (15 A), reducing unexpected downtime. Its non-indicating design minimizes panel lighting needs, while standard packaging and catalog alignment with the Bussmann series simplify stocking and replacements, lowering maintenance time and inventory costs in high-uptime manufacturing environments.
