Eaton FRN-R-1-1/2 Fuse - RK5 Time-Delay, 200 kAIC CE
Part Number: FRN-R-1-1/2
Quick Summary
Eaton Bussmann FRN-R fuse delivers time-delay, current-limiting protection for control circuits in industrial panels. Engineers often battle nuisance trips during motor startups and brief surge events, while needing compact, reliable protection that fits standard enclosures. This FRN-R RK5 device aligns with CE marking and RK5 class operating standards, offering an interrupt rating up to 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc. By combining precise protection with a small form factor, it supports low total cost of ownership, streamlined procurement, and easier replacement. In addition to core protection, the FRN-R-1-1/2 supports efficient panel layouts and safer maintenance in high-availability applications, making it a strong fit for modern control systems and machine safety architectures.
