• 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.
