Bussmann FRNR200 Fuse

The FRN-R-200 (often listed as FRNR200) is a Bussmann/Eaton FRN-R RK5 class fuse sized as a 200 A, 250 VAC time-delay, dual-element cartridge fuse, designed for protection in high-inrush AC circuits. It is a non-indicating, current-limiting device with an interrupting rating of 200 kA at 250 VAC and 20 kA at 125 VDC, making it suitable for demanding industrial applications and panel protection. The FRN-R family is characterized by time-delay operation and dual-element construction within the RK5 fuse class, providing reliable protection for loads with brief surge currents. Available from major electronics and industrial outlets, this 200 A fuse is documented in retailer listings and data sheets as FRN-R-200 with 250 VAC and 125 VDC ratings. Typical applications include AC power distribution, motor drives, and protection panels and equipment where higher interrupt capability and inrush tolerance are required.
