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 are single, double, triple or quadruple barrels 3 in diameter with end mounts designed for bolting directly to equipment bus or terminal pads.
