Current-limiting A2K and A6K fuses provide excellent protection where high available short circuit currents exist. These fast-acting fuses are particularly good for branch/feeder circuits and back-up protection. FEATURES/BENEFITS:

  • Rejection style design prevents replacement by other fuse classes
  • Fiberglass body provides dimensional stability in harsh industrial environments
  • Easy-to-read imprint label for quick recognition and replacement
  • High degree of current limitation for low peak let-thru current RATINGS: A2K
  • Volts: 250VAC / DC
  • Amps: 1 to 600A
  • IR: 200kA I.R. AC, 20kA I.R. DC A6K
  • Volts: 600VAC / 300VDC
  • Amps: 1 to 600A
  • IR: 200kA I.R. AC, 20kA I.R. DC HIGHLIGHTS
