A2K20R Fuse - Fast-Acting - Class RK1

250 Volt - 20 Amp - 200kA I.R. AC - 10 Pack - Mersen


This Mersen A2K20R 20-amp fuse provides excellent protection where short-circuit currents exist. This fast-acting, class RK1 fuse employs Amp-Trap technology, which minimizes 200kA of let-thru current flowing downstream, while its fiberglass body provides stability in rough environments. This 250-volt, fast-acting fuse is great in branch/feeder circuits and back-up protection, and is ideal in application such as loadcenters, panelboards, and switchboards. Sold only by the pack of 10
