FRN-R-5 Description

Short technical summary and product information.

The Eaton Bussmann FRN-R-5 is a 5 amp, 250VAC/125VDC cartridge fuse belonging to the RK5 class. It features a slow-blow (time-delay) response characteristic, making it suitable for circuits with inrush currents. The fuse offers a high interrupting rating of 200kA at 250VAC and 20kA at 125VDC, providing robust overcurrent protection in industrial and electrical applications.

 

This fuse requires a separate holder for mounting and is packaged in a non-standard cartridge form factor measuring 14.22mm in diameter and 50.8mm in length. It carries approvals from CE, CSA, and UL, ensuring compliance with major safety standards.

 

Designed for use in electrical and industrial equipment, the FRN-R-5 is a dual-element time-delay fuse that can handle temporary overloads without nuisance opening, while still providing reliable short-circuit protection.
