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.
