Features
  • Fast short circuit protection and dual element, time delay performance provide ultimate protection
  • Insulated end caps reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing
  • Current limitation protects downstream components against damaging thermal and magnetic effects of short circuit currents
  • 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 co-ordination easy
  • Time delay permits 130% FLA sizing for back-up motor protection
  • Inventory consolidation of class RK1/RK5/H fuses for reduced SKU investment and minimizing potential for misapplying fuse
  • Separate overload and short circuit elements provide time delay for close sizing of high inrush loads linked with RK1 current-limitation and selective co-ordination ratio of 2:1 (within Low-Peak™ fuse family) helps prevent widespread blackouts
  • Protects against 1 ph motor damage
  • Proper sizing can provide "no damage" type 2 co-ordinated protection for NEMA and IEC motor controllers
  • Electrically isolated end caps for additional safety
