Benefits
Separate overload and short-circuit elements provide time-delay for sizing as close as 125 percent of motor FLA
2/1 selective coordination amp ratio (within the Fusetron RK5 fuse family) helps prevent overcurrent events from opening upstream Fusetron fuses
Insulated end caps for 225A-600A (FRN-R) and 65A-600A (FRS-R) fuses reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing
