4800V R-RATED FUSE 18R

4800V R-RATED FUSE 18R

Item #: A480R18R-1

Supplier Part #: A480R18R-1
Brand: Mersen

Mersen 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. These fuses come with a 3 (size D) or 4 (size E) inch diameter barrels with ferrules and are mounted in spring reinforced clips

Blown-fuse indicator to give positive identification of open fuse; On all other 3” barrels if a hookeye is required, use the operating eye 9F61AAW612; Current-limiting for superior equipment protection; The Amp-Trap and 9F60 R-Rated fuses are UL Recognized; Ferrule mounting for standard clips and interchangeability with other brands of fuses; Amp-Trap: UL File E93367; 9F60: UL File E191980; On the 4.8kV an optional hookeye mounted in the factory is available; Metal embossed catalog number and manufacturing date for lasting identification
