Current Limiting Fuses and Breakers reduce the let through fault current. By reducing the fault current, you reduce the Incidend Energy (arc flash).

IEEE 1584 did some testing with current limiting fuses and published a few equations. Properly applied C.L. breakers and fuses can significantly reduce the incident energy.
