Hmm this is a brand new and slightly undersized installation.
It also looks from the pic as if the overload is not equal on all 3 phases. Is the meter showing the hottest phase ? a pair of 120mm tri-rated tails is not quite enough for 1kA, you may manage better with 2 lots of 185 or even 240mm2 depending if the load is sharing equally, and how good is airflow. ( some typical rating data)- though the fact they look more cooked near the termination is telling. I also wonder how sound the crimping is
