Eaton FNQ-R-17-1/2 Fuse - 200 kAIC, 600 V
Part Number: FNQ-R-17-1/2
Quick Summary
The Eaton FNQ-R-17-1/2 fuse delivers reliable overcurrent protection for small control circuits and industrial branch wiring. Engineers often face nuisance trips or downtime when protection is slow to react to startup surges, so selecting a current-limiting, time-delay solution is critical. This device is CE marked and RoHS compliant, supporting European regulatory compliance and sustainability goals. With Class CC designation and current-limiting, time-delay performance, it enables predictable protection coordination while simplifying field replacement and maintenance planning for mixed loads and evolving controls environments.
