Let through Energy - Cable Sizing

Why let through energy of cable is calculated and compared against protective device let through energy, when adiabatic equation and disconnection time check is used to verify the cable sizes? or this let thru energy verification is applied only for current limiting breakers / fuses?

    The device let through time is for circuit breakers and short disconnection times.
