FRS-R-20 Description

Short technical summary and product information.

The Eaton Bussmann FRS-R-20 is a 20 amp, 600VAC/300VDC rated RK5 class cartridge fuse designed for overcurrent protection in electrical and industrial applications. It features a slow-blow (time-delay) response characteristic, making it suitable for circuits with inrush currents.

 

This fuse offers a high interrupting rating of 200kA AC and 20kA DC, providing robust fault current protection. It requires a separate holder for mounting and has a body size of 0.810" diameter by 3.00" length (20.57mm x 76.20mm).

 

The FRS-R-20 carries approvals from UL, CSA, and CE, and is RoHS3 compliant with MSL 1 (unlimited) and REACH unaffected status. It is intended for use in electrical distribution panels, motor control centers, and other industrial power systems.
