Features
  • Application : Power Panelboards / Combination Starters / Motor Control Centers / Machinery Disconnects
  • Separate overload and short-circuit elements provide time delay for sizing as close as 125% of motor FLA
  • Class RK5 current limitation
  • 2:1 selective coordination amp ratio (within the Cooper Bussmann RK5 fuse family) prevents overcurrent events from opening upstream Fusetron fuses
  • Insulated end caps for 225A-600A fuses reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing
