Eaton FNQ-R-7 Class CC Fuse - 200 kAIC Interrupt
Part Number: FNQ-R-7
Quick Summary
FNQ-R-7 is a Class CC time-delay fuse designed to protect industrial control circuits and small transformers. Engineers often struggle with nuisance tripping from inrush currents and the need for predictable interruption during faults. This device features RoHS compliance and CE marking, plus a 200 kAIC interrupt rating at 600 V to support safety and reliability in demanding environments. Its compact form and rejection-style design translate into easier installation and robust protection across line protection, small control transformers, and industrial control panels. By combining precise current limiting with durable construction, the FNQ-R-7 delivers meaningful business value through reduced downtime and safer, compliant electrical protection.

FAQs
Install the FNQ-R-7 in a Bussmann-series compatible panel using standard fuse holders. Ensure correct orientation and that the rejection-style design aligns with the enclosure layout to avoid misinsertion. Verify 600 V rating and 7 A rating match the circuit requirements, and confirm the upstream protection coordination to prevent nuisance outages while preserving fault isolation.
The FNQ-R-7 is a 7 A, 600 V Class CC fuse with a 200 kAIC interrupt rating and a time-delay, dual-element design. These specs enable safe interruption of high fault currents, accommodate inrush in motors and transformers, and deliver reliable protection for line circuits and small control loads in industrial applications.
Yes. The FNQ-R-7 carries RoHS compliance and is CE marked, meeting European regulatory requirements. This makes it suitable for global manufacturing environments and simplifies cross-border procurement and distribution of protection devices in multinational facilities.
Ideal for line protection, small control transformers, industrial control circuits, and branch circuits. The device’s time-delay response and current-limiting features help manage inrush, protect downstream equipment, and support safe startup sequences in automation panels and process lines.
