Eaton FNQ-R-1-1/2 Fuse - Class CC, 200 kAIC
Part Number: FNQ-R-1-1/2
Quick Summary
Eaton FNQ-R-1-1/2 fuse protects small control circuits with time-delay current limiting. Engineers frequently face nuisance trips during equipment startups due to inrush; this device offers selective fault protection without compromising startup reliability. CE marking and RoHS compliance accompany its robust 200 kAIC interrupt rating at 600 V, aligning with safety and regulatory requirements. Class CC construction and ferrule-end connections simplify mounting in standard control panels, reducing installation time and field errors. Featuring a rejection-style design, it helps prevent incorrect replacements while supporting predictable maintenance and procurement workflows. In practice, specifying this fuse translates to improved uptime and consistent protection for line transformers and branch circuits.

FAQs
The FNQ-R-1-1/2 uses ferrule-end connections, supporting quick insertion into standard terminal blocks common in industrial control panels. With a 1.5 A rating and Class CC construction, it fits compact panel layouts while delivering reliable time-delay protection for small transformers and branch circuits. Ensure the enclosure is rated for 600 V and verify the line-side wiring adheres to applicable electrical codes.
Key specs include a 1.5 A amperage rating, Class CC fuse construction, 600 V voltage rating, 200 kAIC interrupt rating, time-delay current-limiting behavior, and a 12-second response at 200% overload. The device uses ferrule-end connections and is non-indicating, suitable for line protection and industrial control applications requiring controlled fault clearing without nuisance trips.
Yes. The fuse is specifically designed for line protection, small control transformers, industrial control circuits, and branch circuits. Its current-limiting, time-delay characteristics help manage transformer inrush while protecting downstream devices. The rejection-style feature reduces misreplacement risk in mission-critical panels, contributing to safer, more reliable operation in industrial environments.
The FNQ-R-1-1/2 is CE marked and RoHS compliant, ensuring compliance with European safety, health, and environmental standards. These certifications support regulatory approvals, safer material usage, and easier global procurement for projects requiring certified components in control panels and machinery.
The fuse’s high interrupt rating and time-delay behavior reduce downtime by preventing unnecessary outages during startup while still delivering fast fault clearance. Its standard ferrule-end design, non-indicating indicator, and rejection-style feature streamline replacements and maintenance workflows, lowering labor costs and improving overall system availability in industrial facilities.
