Features and benefits

•

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.

•

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.
