Features:

• 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.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 downsizing.
