FRN-R-3-2/10 Description

Short technical summary and product information.

The Eaton Bussmann FRN-R-3-2/10 is a 3.2 ampere, RK5 class cartridge fuse designed for overcurrent protection in electrical and industrial applications. It is rated for 250 volts AC and 125 volts DC, with a slow-blow (time-delay) response characteristic that allows it to tolerate temporary inrush currents without nuisance opening.

 

This fuse offers a high breaking capacity of 200,000 amps AC and 20,000 amps DC, making it suitable for circuits with high available fault current. It is approved by CE, CSA, and UL agencies, ensuring compliance with major safety standards.

 

The fuse has a cartridge, non-standard package with a diameter of 0.560 inches (14.22 mm) and a length of 2.000 inches (50.80 mm). It requires a separate fuse holder for installation and is not a direct plug-in type.
