Eaton FNQ-R-6-1/4 Fuse - Class CC, 200 kAIC
Part Number: FNQ-R-6-1/4
Quick Summary
FNQ-R-6-1/4 fuse provides reliable current-limiting protection for small transformers and control circuits. Engineers often struggle to manage inrush surges without nuisance trips in industrial power feeds. This Eaton Bussmann Class CC time-delay fuse offers robust 6.25 A protection with a 600 V rating and a 200 kAIC interrupt capability. Its rejection-style design reduces incorrect replacements in crowded panels, while ferrule-end terminations simplify field installation and improve contact reliability. Certified with CE marking and RoHS compliance, the FNQ-R-6-1/4 aligns with modern regulatory expectations while delivering predictable protection for line-side and control circuits. For manufacturers and integrators, this fuse translates to lower maintenance costs, reduced downtime, and improved equipment availability.

FAQs
When wiring FNQ-R-6-1/4, use the ferrule-end terminals specified and ensure the device is mounted in a suitably rated holder. The 1.5 in length and 0.41 in cross-section fit standard compact panels. Because it is non-indicating, verify circuit integrity with a meter during commissioning and maintenance, and confirm RoHS/CE compliance in regulated environments.
The fuse employs a time-delay, dual-element design that tolerates temporary inrush currents while still delivering fast fault interruption. This reduces nuisance tripping in motors, transformers, and control circuits during startup, improving uptime and reducing unnecessary maintenance interventions.
The FNQ-R-6-1/4 is CE marked and RoHS compliant, reflecting adherence to essential health, safety, and environmental standards. With a 600 V rating and a 200 kAIC interrupt capability, it meets typical industrial protection requirements for machinery, panels, and control systems.
This fuse provides 6.25 A protection at up to 600 V with a 200 kAIC interrupt rating, suitable for line protection, small control transformers, branch circuits, and industrial control panels. Its rejection style reduces incorrect substitutions, aiding reliable, long-term protection in automation architectures.
The non-indicating design lowers ongoing monitoring needs, while the durable melamine tube and ferrule terminations simplify replacement and installation. The combination of robust fault handling and reduced nuisance trips translates to lower downtime, fewer field service calls, and improved overall equipment effectiveness (OEE) in manufacturing environments.
