Eaton FNQ-R-5-6/10 Fuse Time-Delay - Class CC, 200 kAIC
Part Number: FNQ-R-5-6/10
Quick Summary
The Eaton FNQ-R-5-6/10 fuse provides time-delay current-limiting protection for industrial control circuits. Engineers often struggle with nuisance trips during motor starts and transformer inrush, leading to costly downtime. CE marking and RoHS compliance help meet global safety and environmental requirements, while a 600 V rating supports industrial use. This fuse pairs with Bussmann series data and standard ferrule-end connections for straightforward installation and reliable protection across control panels. In practice, the FNQ-R-5-6/10 reduces nuisance trips, improves uptime, and simplifies spare-part management across scalable automation setups. Its ferrule-end connections and compact 1.5 inch length support fast retrofit, while the 12 second response at 200% delivers predictable protection.
