Special Features

  • Consistent 2:1 ampacity ratios for all Low-Peak® fuses make selective coordination easy
  • Current limitation protects downstream components against damaging thermal and magnetic effects of short circuit currents
  • Dual element fuses have lower resistance than ordinary fuses, hence they run cooler
  • Fast short circuit protection and dual element, time delay performance provide ultimate protection
  • Industry's only UL listed and CSA Certified fuse with a 300 kA interrupt rating that allows for simple, worry free installation in virtually any application
  • Long time delay minimizes needless fuse openings due to temporary overloads and transient surges
  • Proper sizing can provide "No Damage" type 2 coordinated protection for NEMA® and IEC® motor controllers
  • Reduces existing fuse inventory by up to 33% when upgrading to Low-Peak® fuses
  • Selective coordination ratio of 2:1 (within Low-Peak® fuse family) prevents electrical shutdowns from extending beyond the failed circuit
  • Separate overload and short circuit elements provide time delay for sizing of high inrush loads linked with class J current limitation
  • Series combination ratings with branch circuit breakers allows broad range of coverage, independent of breaker manufacturer
  • Space saving package for equipment down sizing
  • They can often be sized for back up protection against motor burnout from overload or single phasing if other overload protective devices fail
