Carton Quantity

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. They 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.
