It is inverse in the sense , the tripping time will decrease as the magnitude of fault current increase.
simply saying,
"for a fault current of 25KA-the time delay may be 2s.
& for a fault current of 30KA the tme delay may be 1.5s.thus as the fault current increases the time delay decreases.

My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.
