• 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.
