How Can we know and decide to replace MCCB for what kind of overheating condition?

What is the acceptable temperature (refer to I.R reading data ) for MCCB?


<In 3 poles MCCB , 63 Amp ABB brand using with 16 mmsq cables>


In my case, one of the Phase contact got Hot Spot due to the cable cap was inserted together with copper when installation and continuous using .
