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.
Features/Benefits:
environments
•
Rejection style design prevents replacement by other fuse classes
•
Fiberglass body provides dimensional stability in harsh industrial
•
Easy-to-read imprint label for quick recognition and replacement
•
High degree of current limitation for low peak let-thru current
