Eaton FNQ-R-1-1/8 Fuse - Class CC Time-delay, 200 kAIC
Part Number: FNQ-R-1-1/8
Quick Summary
The Eaton FNQ-R-1-1/8 fuse is a current-limiting solution designed for line protection in small control panels and industrial transformers. In practice, engineers struggle with nuisance trips during inrush or miscoordination between upstream and downstream devices; this fuse’s time-delay, dual-element construction helps tolerate brief surges while preserving critical protection. This device is CE marked and RoHS compliant, supporting regulatory compliance across global markets, and it carries a 600 V rating with a robust 200 kAIC interrupt rating. By pairing these specifications with a compact ferrule-end design, the FNQ-R supports easy installation, reliable operation in tight spaces, and reduced total cost of ownership for panel builders and OEMs.

Bussmann series FNQ-R Class CC Fuse Data Sheet No. 1014
Feature → Business Impact → Application: The FNQ-R-1-1/8 uses a dual-element, current-limiting time-delay design that tolerates inrush surges without sacrificing fast fault clearing, improving equipment uptime and reducing nuisance trips in control panels and small transformers. This translates to measurable downtime reductions and smoother startup sequences in industrial automation workflows, particularly where transformer inrush is common. Feature → Business Impact → Application: With an interrupt rating of 200 kAIC at 600 V, this fuse delivers high fault-current protection, safeguarding downstream devices and wiring from catastrophic damage while maintaining selectivity in mixed circuits found in branch protections and industrial control circuits. Feature → Business Impact → Application: Ferrule-end x ferrule-end connections simplify installation in standard Bussmann FNQ-R assemblies, enabling quick panel integration, reliable mating with existing conduit fittings, and improved vibration resistance in harsh factory environments. Feature → Business Impact → Application: The rejection-style format minimizes the risk of incorrect fuse installation in multi-fuse panels, reducing maintenance errors and ensuring proper protection coordination across feeders and control circuits. Feature → Business Impact → Application: RoHS compliant and CE marked, the FNQ-R aligns with environmental and safety standards while supporting global procurement strategies and regulatory compliance for multinational OEMs. Feature → Business Impact → Application: With a 1.125 A rating and a 12-second response at 200% load, designers can optimize protection without derating nearby components, enabling smaller controllers and compact power supplies in line protection and branch circuit applications.

FAQs
The FNQ-R-1-1/8 is designed for line protection in small control panels and industrial transformers. It uses ferrule-end connections and a current-limiting, time-delay design to tolerate inrush while preventing unnecessary trips, making it suitable for feeder and branch circuit protection in compact automation enclosures.
Key specs include a 1.125 A rating, 600 V voltage rating, 200 kAIC interrupt rating, and a 12-second response time at 200% overload. It is a dual-element, current-limiting time-delay fuse with a non-indicating indicator, designed to balance inrush tolerance with rapid fault clearing in industrial circuits.
Use in line protection for small control transformers, branch circuits, and industrial control panels. Its Class CC format and current-limiting characteristics support selective coordination in feeders, reducing damage from short circuits while allowing downstream devices to continue operating during transformer inrush events.
The FNQ-R-1-1/8 is CE marked and RoHS compliant, ensuring regulatory conformity for global panels and exportable assemblies. These certifications support environmental and safety requirements, simplifying procurement for multinational facilities and integrators.
By tolerating inrush with time-delay while providing high fault protection, it reduces nuisance trips and equipment wear, lowering maintenance costs and downtime. The rugged ferrule-end design also facilitates quick, reliable installations, contributing to faster panel builds and better overall return on investment for OEMs and maintenance teams.
