Eaton FRS-R-25 Fuse - 200 kAIC at 600 Vac RK5

Time-delay, dual-element design provides selective coordination for motor loads, helping protect motors while avoiding premature trips. This translates to fewer nuisance interruptions during normal startup sequences and load transients, reducing wear on contactors and drives. In practice, the FRS-R-25 is well suited for control panels, motor control centers, and feeder circuits where accurate protection is required without compromising productivity. Industry engineers value the predictable response of RK5 fuses in mixed loads. High interrupt ratings support protection in high fault current environments. With 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc, the fuse can halt serious faults quickly, limiting collateral damage to downstream equipment. This capability lowers repair costs and downtime after a fault, while enabling more compact layouts since upstream protection can be sized for demanding conditions. Typical applications include large power distribution panels and switchgear assemblies in manufacturing facilities. Class RK5 and ferrule-end terminations enable straightforward integration into standard Bussmann catalog holders. Non-indicating fuses simplify visual checks during routine maintenance, while the ferrule-to-ferrule connection provides a robust, vibration-tolerant interface in panel enclosures. The 5 inch length and compact 0.81 in footprint fit common fuse holders, reducing installation time and stocking complexity for spare parts. Operational performance is tuned for real-world industrial duty. The 10 second response time at 500% overload offers a controlled delay that balances protection against nuisance trips with fast clearing during genuine faults. CE marking reinforces regulatory alignment and supports compliant procurement across multiple sites.
