If the circuit composition leaves you with a high short circuit availablity at a piece of equipment, you are pretty much stuck with it. You could install an in-line reactor, but it is large, cause voltage problems and mostly not worth it. If you could rerun the feeder or circuit to the equipment, take the long road, since conductors have lots of resistance.
Mostly you need to deal with the availability of the fault current. Many times you could research a fuse to put in series with the down stream breaker to achieve series rating. Don't fall into the false perception that a current limitting fuse by itself will limit the available current, 'cause it will not. You must have a listed combination to have a series rating.
