Features(1/10-60A):

• 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.
