Eaton KWS-R-6 Fuse - Class RK1, 200 kAIC, 600 Vac

High interrupt rating delivers robust protection with a 200 kAIC at 600 Vac capability, dramatically reducing downstream equipment damage and unplanned outages. This translates to improved system uptime and lower maintenance costs in PV sites, inverter rooms, and panelboard assemblies. The result is safer fault isolation and better protection coordination across mixed DC/AC protection schemes, a crucial advantage for industrial solar integrations. The Class RK1 designation provides predictable protection class compatibility with common fuse blocks, ensuring straightforward engineering and panel layout without complex coordination. Its non-indicating design minimizes panel clutter while simplifying status monitoring across distributed protection networks, shortening troubleshooting cycles and boosting overall reliability. The 6 A rating supports precise fuse sizing for PV strings and inverter inputs, helping engineers optimize selectivity and reduce nuisance trips in dynamic solar installs. Compact packaging, 5 in length, and a light 0.13 lb weight enable easy mounting in tight enclosures and standard commercial electrical panels, accelerating commissioning. CE marking confirms compliance with essential European safety rules, supporting cross-border deployments and supplier audits. The fuse fits standard Bussmann line expectations, delivering consistent performance in photovoltaic systems, inverters, and panelboards while maintaining cost-efficient stock and spares.
