You limit the SCCA by having "selective coordination" in your fuse /breaker selections.Simply put, the upstream overcurrent device is sized according to its' response curve, so it will trip before the short circuit draws 10,000 amps.
Usually, this means the appropriate fuse in your disconnect. Your Bussman rep can steer you to the right fuse - and the Bussman site has plenty of stuff to read on the topic
