1 A240R/A480R/A072F/A072B MED. VOTAGE FUSES / R-RATED R-RATED MOTOR STARTER FUSES Amp-trap R-rated fuses are current-limiting, high interrupting rating fuses intended for the short-circuit protection of medium voltage motors and motor controllers. R-rated fuses are back up fuses that have a minimum interrupting rating, and must be coordinated with overload relays in combination motor starters. The motor starter manufacturer generally specifies the R-rated fuse size. Amp-trap R-rated fuses are rated 2R to 6R, at 2.4, 4.8, and 7.2kV. 4.8 and 7.2kV fuses are U Recognized. The 4.8kV (A480R) is available with hookeye tab. The 7.2kV (A072F) series has the same dimensions as the 4.8kV (A480R), allowing smaller 7.2kV equipment or 4.8kV upgrades. The A072B is available as a bolt in version E HIGHIGHTS: R-Rated U Recognized in 4.8 and 7.2kV ratings APPICATIONS: Short circuit protection of medium voltage motors and motor controllers Features/ Benefits Ferrule mounting for standard clips and interchangeability with other brands of fuses 7.2kV A072F series has the same dimensions as 4.8kV fuses, allowing compact, higher voltage rated designs A072B optional bolt-in design for improved design flexiblity Optional hookeye on A480R for non load-break isolation by hookstick Ratings Approvals A240R AC: 2R to 6R 2750V, 45kA I.R.
