Bussmann FRS-R-100

Bussmann FRS-R-100

Overview

The Bussmann FRS-R-100 is a Class RK5 dual-element fuse designed for reliable overcurrent protection in industrial and commercial power distribution systems. Rated at 100 A, it provides protection for both overload and short-circuit conditions with a voltage rating of 600 V AC and 300 V DC. Its high interrupt rating of 200 kAIC at 600 V AC ensures safe operation under heavy fault conditions.

Compact and durable, the FRS-R-100 features a blade end x blade end connection for secure installation. As a dual-element fuse, it offers time-delay performance—with a 10-second response at 500% overload—making it ideal for motor and transformer protection where inrush currents are common.
