AMP-TRAP
®
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 let-
thru current
