Eaton Specification Sheet - FNQ-R-2-R1
Current-limiting high inrush time-delay fuse reduces nuisance trips and limits arc damage, improving equipment uptime in line protection and industrial control panels. This translates to fewer unplanned outages during motor starts and transformer energization, while still providing fast fault isolation. Application: line protection, small control transformers, and industrial control circuits. 2 A amperage rating with Class CC construction ensures precise protection for compact control transformers and low-current circuits. The result is reliable coordination with upstream protections and minimal voltage drop during normal operation. Application: small- to mid-size control panels, branch circuits, OEM equipment. RoHS compliance reduces regulatory risk and simplifies sourcing across manufacturing sites. The fuse's compact footprint and standard Bussmann series compatibility ease procurement and field replacements. Application: panel-mounted fuse protection in tight enclosures. The standard catalog reference FNQ-R-2-R1 with UPC 051712509497 simplifies ordering and stocking.

FAQs
FNQ-R-2-R1 fits compact control panels with a 1.5 in length, 0.41 in width, and 0.41 in height, providing a 2 A current-limiting protection level ideal for small transformers and branch circuits. Its Class CC design aligns with Bussmann series practices for predictable replacement and coordination with upstream protections.
The FNQ-R-2-R1 combines current-limiting capabilities with a time-delay response, allowing short startup surges without tripping while rapidly isolating faults beyond the threshold, reducing downtime and arc energy in line protection and industrial control circuits.
Yes. With a 2 A rating and Class CC construction, FNQ-R-2-R1 is well-suited to limit fault current while accommodating inrush characteristics typical of small control transformers in control panels and industrial equipment.
The data indicates RoHS compliance for environmental regulation alignment. For additional standards such as CE or UL, consult Eaton's datasheet or the manufacturer catalog to verify current listings for your region and application.
Procure using catalog FNQ-R-2-R1 with UPC 051712509497. Confirm 2 A amperage rating, 1.5 in length, 0.41 in width/height, and Class CC. Install in line protection or branch circuits within industrial control panels, ensuring proper fuse holder compatibility and clearance.
