  • 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. 6.0" 8.0" 3.75" 0.69" 2.13" 0.38" 0.53" 2" 2.5" 7.13" 5.25" 3.38" 0.53" 1.63" 1.88" 0.41" *2" 0.25" 5.75" 4.38" 3.0" 0.38" 1.38" 1.13" 0.28" 0.19" 1.5" 4.63" 3.63" 2.63" 65 to 100A 0.28" 0.75" 1.13" 0.13"1"0.38" 110 to 200A 225 to 400A 450 to 600A
