NFPA 70E Table 130.7(C)(15)(a) Question

I would like a clarification on Table 130.7(C)(15)(a). As an example, the first entry is:

Panelboards or other equipment rated 240 volts and below

Parameters: Maximum of 25 kA available fault current; maximum of 0.03 sec (2 cycles) fault clearing time; minimum working distance 455 mm (18 in.)

 

Does the fault clearing time "maximum of 0.03 sec (2 cycles)" apply to the maximum available fault current? This would make sense since the table is used as an alternative to calculating the arcing fault current. But I would like confirmation that this is the correct approach.
