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
No.
Selective coordination has nothing to do with fault current reduction. It has to do with which device opens in which sequence.
Fault current reduction requires the upstream device must limit its let through current as well as its peak current. Simply choosing a target value, like 10,000A, is not sufficient. At a minimum you still need to know the available fault current. This is why UL, and to a major extent the NEC, requires testing of all series-combinations of protective devices.
Bussmann's SPD (2009 page 77) has information on the use of current limiting fuse Let-Through charts. Protection of equipment (e.g. control panels) has a separate section, which deals with using umbrella fuse let through charts.
