Yes Where the required current rating to protect the motor circuit is greater than the largest fuse rating, two or more fuse links may be connected in parallel as required. Due to proximity heating effects, the combined rating of the combination will usually be somewhat less than n x the rating of each fuse, where n = number of fuses in parallel. In this case, ask the manufacturer for details.
