A2K-R & A6K-R
Fast Acting/Class RK1
These fast-acting fuses deliver a high degree of current
limitation where you need it most
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.
