Features

  • Separate overload and short-circuit elements provide time delay for close sizing of high inrush loads linked with RK1 current-limitation and selective coordination ratio of 2:1 (within Low-Peak fuse family) prevents widespread blackouts
  • Inventory consolidation of Class RK1, RK5 and H fuses for reduced SKU investment and minimizing potential for misapplying fuse
  • 300kA RMS symmetrical interrupting rating provides adequate ratings without obsolescence for all electrical systems, big or small
  • Insulated end caps reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing
