Safety
• 200,000 A.I.R. — Reliable interruption of all overcurrents up to
200,000 amperes.
• Faster acting short-circuit protection than any non-current-limiting
mechanical protective device.
Reliability
• Accurate and reliable — Automated, precision manufactured and
assembled parts ensure accurate, consistent response to overloads
and short-circuits.
Longer Equipment Life
Littelfuse FLNR/FLSR series fuses have been the superior UL Class
RK5 dual-element time-delay fuses, and are the most widely used class
of fuses. FLNR/FLSR series fuses provide excellent protection for all
types of circuits especially those containing motors. However, users and
specifiers should consider the significant benefits offered by Indicator
fuses. Complete information on these fuses may be found earlier in this
section.
• Reduced damage to equipment caused by heating and magnetic
forces of short-circuits.
• Equipment runs cooler with low-resistance dual-element fuses.
