Eaton FNA-6 Fuse - 6 A Dual-Element CE Marked
Part Number: FNA-6
Quick Summary
Eaton Bussmann FNA fuse provides time-delay protection for inductive loads in control panels. Engineers often contend with nuisance trips caused by startup surges, and a fast-acting device isn’t always the right fit for motor and relay circuits. This dual-element, CE-marked fuse helps balance reliability with protection, offering robust overload control while tolerating brief inrush events. While CE compliance is documented, there are no listed SIL or IP certifications in the provided data; nonetheless, the FNA-6 aligns with standard European safety expectations for industrial protection. For ongoing uptime, it integrates seamlessly with ferrule-end wiring and standard fuse holders, delivering predictable behavior in automation equipment and panel assemblies.

FAQs
To install the FNA-6 fuse, power down the equipment and open the fuse holder. Insert the ferrule-end of the fuse into the holder, ensuring the ferrule ends are fully seated with clean, undamaged surfaces. The silver-plated pins help maintain a low-resistance connection, aiding reliable seatment. Close the holder and restore power, verifying operation at the panel level.
The FNA-6 is designed for inductive load circuits and electronic control paths within industrial panels. With a 6 A rating and time-delay (dual-element) design, it tolerates startup surges typical of motors and relays while protecting circuitry from sustained faults. It is well-suited for control panels, automation gear, and other equipment in manufacturing environments.
The data confirms CE Marked compliance, indicating conformity with European safety standards. There is no explicit listing for SIL, IP ratings, or UL/CSA in the provided data. For projects requiring additional certifications, verify with Eaton or a procurement specialist and consider supplementary protective components where needed to meet all regulatory or industry-specific requirements.
Time-delay (dual-element) fuses like the FNA-6 tolerate brief inrush currents common to motor start-up without tripping, while still interrupting faults promptly. This reduces nuisance outages and wear on contactors. In practice, it improves panel reliability and extends equipment life by preventing unnecessary shutdowns during normal loading conditions.
Regular inspection of the fuse path, ferrule ends, and adjacent connections is recommended. Check for signs of overheating, discoloration, or corrosion on ferrule terminations and pins. Keep the fuse and holder clean and free of debris, and replace any unit showing physical damage or inconsistent seating to maintain consistent protection levels in critical automation circuits.
