The current limit is not configurable, but the fault shut-off time is. You can set the fault shutoff time as low as 500 ms.

I am not familiar with the proper WPI Library calls to set this parameter, maybe someone else can comment.

The over current protection uses a timer to count how long the Jaguar is operating above the limit. This timer follows an exponential equation that intersects at 60A and 2 seconds. Above 60A the Jaguar will shut off at exponentially smaller time periods. For >100A the time until shutoff is quite short.
