Eaton KWN-R-30 Fuse - Class RK1, Non-indicating, 30A
Part Number: KWN-R-30
Quick Summary
KWN-R-30 fuse provides fast protection for industrial control circuits in panelboards and motor drives. Engineers frequently contend with nuisance trips and short fuse life in harsh industrial environments, so reliable selectivity matters. There are no specific SIL, CE, or IP certifications listed for this unit; it uses a Class RK1 fast-acting design and a non-indicating indicator to simplify implementation. The device’s compact 2 in length and standard packaging support easy retrofits and reduced enclosure footprint, while the Bussmann series lineage informs long-term spare-part compatibility. For procurement teams, this fuse delivers predictable replacement cycles, broad catalogue support, and a straightforward path to compliant circuit protection without over-engineering protection schemes.

Eaton Specification Sheet - KWN-R-30
Compact form factor with standard packaging enables faster panel integration and easier field swaps. The 2 in length with 0.56 in width and height minimizes enclosure footprint, reducing cabinet space costs and enabling denser control architectures in panelboards and motor drives. This size translates to straightforward retrofits and broad compatibility with common Bussmann catalog parts. The 30 A amperage rating ensures reliable protection under typical fault currents, improving selective coordination with upstream protection and reducing unnecessary system-wide trips in automation lines. Class RK1 design provides predictable fuse curves, supporting safer maintenance windows and easier engineering justification. The non-indicating indicator reduces panel cosmetic complexity, while maintaining clear protection performance. The Limitron fast-acting performance rapidly interrupts fault energy, protecting sensitive devices and extending system life in motors and drives. Documentation and catalog availability streamline procurement and compliance processes, ensuring consistent sourcing across projects and sites.

FAQs
The KWN-R-30 is a compact 2 in long fuse with a 0.56 in width and height, designed for standard panelboard slots and Bussmann catalog compatibility. Plan for a clean, accessible mounting area and ensure downstream wiring is sized for 30 A protection. The non-indicating design means status signaling should be provided via upstream indicators or separate monitoring, not on the fuse itself.
The fuse is rated at 30 A with Class RK1 classification, a standard Bussmann fast-acting design, and a non-indicating indicator. The body dimensions are 2 inches in length and 0.56 inches in both width and height, with a weight of approximately 0.4 lb. These specs support predictable trip curves and straightforward replacement in typical control circuits.
Yes. With a 30 A rating and fast-acting Limitron performance, the KWN-R-30 is appropriate for protecting motor control centers and automation feeders against overcurrents. Its compact form factor helps when space is limited in control panels, and its standard packaging facilitates easy field replacements.
There are no specific SIL, CE, or IP certifications listed for this unit in the provided data. It uses the RK1 fuse class design and a non-indicating indicator. If certifications are a strict requirement, verify with Eaton/Bussmann catalogs or request formal certification documentation before procurement.
Stocking the KWN-R-30 alongside other Bussmann Limitron fuses simplifies maintenance planning due to catalog compatibility and standard packaging. The 30 A rating and fast-acting protection reduce fault energy exposure, potentially lowering downtime and maintenance costs. Access to Eaton’s specification sheets and catalogs supports quick sourcing and consistent labeling across sites.
