Bussmann NSB FNQ-R-2-1 Fuses

FNQ-R-2-1/2 is a Bussmann (Eaton) Class CC fuse in the FNQ-R series, designed for line protection and time-delay applications in industrial controls and small transformers. It is a 2.5 A, 600 V AC rated fuse with a 200 kA interrupt rating, built with a melamine tube and ferrule end connections (13/32 in diameter by 1-1/2 in long). This non-indicating, rejection-style fuse complies with RoHS and is CE-marked, making it suitable for use in equipment where reliable, current-limiting protection is needed without indicating the fuse’s status. Common applications include protecting branch circuits, small control transformers, and general industrial control circuits, where a compact Class CC device is preferred for handling inrush conditions while maintaining fast response to overcurrent events.
