Bussmann FRS-R-50

Bussmann FRS-R-50

Overview

The Bussmann FRS-R-50 is a Class RK5 dual-element time-delay fuse designed to provide superior overload and short-circuit protection in industrial and commercial applications. With a 50 A current rating and voltage ratings of 600 V AC and 250 V DC, it delivers reliable circuit protection under demanding conditions. Its 200 kAIC interrupt rating at 600 V AC ensures safe and effective fault clearing.

Engineered with a dual-element design, the FRS-R-50 provides a 10-second response time at 500% overload, making it suitable for inductive loads such as motors and transformers where inrush currents occur. With its ferrule end x ferrule end connection, this fuse installs securely into standard holders, ensuring long-term durability and dependable performance.
