Eaton Cooper Bussmann Low-Peak™ KRP-C Series Current Limiting Fuses 650 A Time Delay 300/100 kA

Mfg #: KRPC650SP
BSE #: 114187

All purpose silver-linked fuse for both overload and short-circuit protection for high capacity systems (mains and large feeders).

  • Time-delay (minimum of four seconds at five times amp rating) for close sizing
  • Current-limiting action of the fuse generally affords considerable reduction in bus bracing
  • Interrupting rating of 300,000 amperes complies with NEC Sections 110-9 and 230-65 for today large capacity systems
  • O-ring seals maximize pressure build-up during current-limiting action and ensure filler retention
  • High grade silica-sand filler, accelerates response of fuse to short-circuits by having quenching effect upon the fuse arc
  • 99.9% pure silver fuselinks, the high conductivity of silver gives low watt loss and low operating temperature at normal current levels, maximizes total clearing I2t fault energy let-through
  • Selective coordination (blackout prevention)
  • Glass melamine tube
  • Silver-plated end bells
