ABB 308X400A Class J GE Controls Adaptor Plate

The CR308X400A is a universal-type adapter plate with hardware for converting to Class J fuses in combination-type magnetic motor starters, NEMA Sizes 0-3. Clips in standard NEMA Size 4 starters can be repositioned to accept Class J fuses without extra hardware. The adapter can be used to convert standard 600-Volt fusible starters by providing for easy relocation of the fuse clips in the starters. For most applications, clip sizes for Class J fuses are the same as those for ordinary NEC fuses. The adapter can also be used to convert nonfusible starters by ordering the proper clips for Type QMR switches. With Class J current-limiting fuses, the starters are rated at 100, 000 Amperes rms symmetrical.
