• Industry’s only UL Listed and CSA Certified fuse
with a 300kA interrupting rating that allows for
simple, worry-free installation in virtually any
application.
• Fast short-circuit protection with time-delay
performance provide ultimate protection.
• Consistent 2:1 ampacity ratios for all Low-Peak
fuses make selective coordination easy.
• Time-delay for close sizing load.
• Current-limiting action of the fuse generally
affords considerable reduction in bus bracing.
• All-purpose silver-linked fuse for both overload
and short-circuit protetion for high capacity
systems (mains and large feeders).
• O-ring seals maximize pressure build-up
during current-limiting action and ensure filter
retention.
• High-grade silica sand filler accelerates
response of fuse to short-circuits by having
quenching effect on the fuse arc.
• 99.9% pure silver links provide low watt loss
with low operating temperature on normal
current levels and minimizes total clearing I²t
fault energy left-through.
