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 and dual-element,
time-delay performance provide ultimate
protection.
Reduces existing fuse inventory by up to 33%
when upgrading to Low-Peak fuses.
Consistent 2:1 ampacity ratios for all Low-Peak
fuses make selective coordination easy.
Long time-delay minimizes needless fuse
openings due to temporary overloads and
transient surges.
Current-limitation protects downstream
components against damaging thermal and
magnetic effects of short-circuit currents.
Dual-element fuses have lower resistance than
ordinary fuses so they run cooler. They can
often be sized for back-up protection against
motor burnout from overload or single-phasing
if other overload protective devices fail.
Proper sizing can provide “no damage” Type
2 coordinated protection for NEMA
®
and IEC
®
motor controllers.
Space-saving package for equipment
