Bussmann FRN-R-20

Overview

The Bussmann FRN-R-20 is a Class RK5 dual-element time-delay fuse designed to provide superior overload and short-circuit protection in industrial and commercial electrical systems. Rated at 20 A, with a 250 V AC and 125 V DC voltage capacity, this fuse ensures reliable operation under demanding conditions. With a 200 kAIC interrupt rating at 250 V AC, it offers strong fault-clearing capability to protect equipment and circuits.

Its time-delay response of 8 seconds at 500% overload accommodates motor and transformer inrush currents without nuisance tripping. Built with a ferrule end x ferrule end connection, the FRN-R-20 installs securely and provides long-lasting durability.
