Agency Information:
CE, Std. 248- 14, UL Listed 1⁄10-8⁄10A, IR 35A@ 250V, IR 10kA@ 125V , 1-15A, IR 10kA@ 125V, Guide JDYX, File 19180, CSA Certified, 0-8⁄10A/250V, 1-10A/125V, Class 1422-01, File 53787.

Genery information:
• Use in power electronic circuits in which there are high inrush currents and fuse openings must be quickly apparent.
• Has silver-plated pin for positive, electrical signal activation.
• FNAs larger than 10 amperes have dual-tube construction.
• Mount in Buss fuseblock 3839 for signal indication.
• Mount in HPF-C panel-mounted fuseholder or BM series fuseblocks for visual indication.

Features and Benefits
• FNA has a pin indicator providing visual identification of failed circuits, resulting in reduced circuit downtime.
• Time-delay response allows close sizing on control transformers and relays

Typical Applications
• Control Circuits
• Electronic Circuits
