Bussmann FRS-R-20

Bussmann FRS-R-20

Overview

The Bussmann FRS-R-20 is a Class RK5 dual-element time-delay fuse designed for reliable circuit protection in industrial and commercial applications. Rated at 20 A, it operates at 600 V AC and 300 V DC, offering dependable overload and short-circuit protection. Its 200 kAIC interrupt rating at 600 V AC ensures robust performance in demanding environments.

With a ferrule end x ferrule end connection, the FRS-R-20 provides secure installation in standard fuse holders. The time-delay design allows a 10-second response at 500% overload, making it suitable for protecting motors, transformers, and inductive loads where inrush currents are common.
