Eaton FNQ-R-9 Fuse - Class CC Time-Delay 200 kAIC
Part Number: FNQ-R-9
Quick Summary
The Eaton FNQ-R-9 fuse provides current-limiting, time-delay protection for line power and small control circuits in industrial controls. Engineers often struggle with nuisance trips during inrush and the challenge of selecting devices that don’t compromise fast fault clearance. The fuse is CE marked and RoHS compliant, aligning with European electrical safety and environmental standards. As part of the Bussmann Series, it delivers proven line protection for transformers, control panels, and branch circuits. With a 9 A rating at 600 V and a 200 kAIC interrupt rating, it helps reduce downtime and simplifies spare-parts budgeting for maintenance teams. This balance of performance and regulatory compliance translates to lower lifecycle costs and fewer field failures.

Bussmann series FNQ-R Class CC Fuse Data Sheet No. 1014
Feature: Time-delay, dual-element current-limiting design enables controlled inrush handling while maintaining fast fault clearance. Business Impact: Smoother startup of small control transformers reduces nuisance trips and extends transformer life. Application: Ideal for line protection and industrial control circuits where brief overloads occur. Feature: Rejection style construction prevents incorrect substitutions, improving panel reliability and maintenance accuracy. Business Impact: Reduces mis-matched fuses and field errors, lowering service time and repair costs. Application: Field service and retrofit projects where component compatibility matters. Feature: 200 kAIC interrupt rating provides robust short-circuit protection for feeders and branch circuits. Business Impact: Enables safer disconnections during high-energy faults, protecting equipment and personnel. Application: Main and branch circuit protection in demanding industrial environments. Feature: Compact form factor with ferrule end connections (1.5 in length, 0.41 in width, 0.41 in height) and melamine tube material. Business Impact: Easy installation in tight control panels and reliable terminal block mating, reducing assembly time. Application: Small control panels and compact industrial controllers. Feature: RoHS compliant and CE marked ensures regulatory alignment for European markets. Business Impact: Simplifies compliance documentation and supplier qualifications while preserving performance. Application: European line protection deployments across industrial controls. Feature: Non-indicating fuse with standard packaging supports predictable maintenance cycles and spare-part planning. Business Impact: Improves inventory control and reduces unexpected downtime. Application: Routine replacements in line protection and branch circuits. In practice, FNQ-R-9 complements Eaton Bussmann data and the FNQ-R family by delivering reliable, regulatory-aligned protection with consistent performance in harsh industrial environments.
