General Purpose US US Fuses General Purpose Fuses American Power Fuses AMP-TRAP(R) A2K and A6K (Class RK1FA) These fast-acting fuses deliver a high degree of current limitation where 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 letthru current Ratings Applications A2K AC: 1 to 600A 250VAC, 200kA I.R.
