Features and benefits
•
Industry’s only UL Listed and CSA Certified fuse
with a 300 kA 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.
•
Time-delay permits 130% FLA sizing for back-up
motor protection.
•
Current-limitation protects downstream
components against damaging thermal and
magnetic effects of short-circuit currents.
•
Protects against single-phase motor damage.
•
Proper sizing can provide “no damage” Type 2
coordinated protection for NEMA and IEC motor
controllers.
