Eaton KWS-R-60 Fuse - Class RK1, 60 A, 600VAC/600VDC
Part Number: KWS-R-60
Quick Summary
The Eaton KWS-R-60 fuse is a 60 A protection device designed for solar PV systems, inverters, and panelboards. Engineers often grapple with selecting fuses that satisfy both DC and AC fault currents while fitting compact enclosures and budgets. This fuse meets CE Marked compliance and uses the RK1 class to deliver predictable response in mixed voltage environments, supporting reliable system protection. With a 100 kAIC at 600 Vdc and 200 kAIC at 600 Vac rating, it provides robust fault-current handling. The result is safer, more maintainable protection that aligns with PV system design goals, while integration with Bussmann series components enhances installation efficiency and long-term cost of ownership.

FAQs
When deploying the KWS-R-60 in a solar PV setup, ensure blade end x blade end connections fit the bus or terminal blocks used by your panelboards. Verify the 600 Vdc and 600 Vac ratings align with your inverter and DC string voltages. Use CE-marked compliance as a baseline for European installations and pair with compatible Bussmann series components to simplify procurement and maintenance.
The KWS-R-60 is rated for 60 A with voltage ratings of 600 VAC and 600 Vdc. Its interrupt ratings are 100 kAIC at 600 Vdc and 200 kAIC at 600 Vac, enabling robust fault-current handling in mixed DC/AC environments typical of PV systems and auxiliary panels.
Yes. The KWS-R-60 is designed for photovoltaic inverters and panelboards, offering a Class RK1 design and blade-end connections that align with Bussmann series protection schemes. Its dual voltage capability and high interrupt ratings support both DC side protection and AC distribution, reducing the need for multiple fuse types in mixed-voltage installations.
The KWS-R-60 carries CE Marked compliance, indicating conformity with applicable European safety standards. While the product’s primary classification is RK1, the CE mark facilitates regulatory acceptance in EU markets and supports broader international procurement when paired with standard Bussmann series components.
The KWS-R-60’s high interrupt ratings and blade-end design streamline maintenance by allowing quick, predictable operation during faults and faster replacements. Its non-indicating status reduces false indicators in some configurations, while CE compliance supports faster project sign-off. Over time, this translates to reduced downtime, lower labor costs, and a lower total cost of ownership for PV protection schemes.
