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.
