Dear Ashfaq, thanks for you interest. 440V AC is normally not used in control panel . As you know control panel contains the Analogue input signal, 440V Ac supply contains the emf it may cause distortion in the signal, also this emf can effect the cards and controller so we keep this wire separate from control panels. I will make a detail video, in which I will describe why we not use a three phase supply in control panel what must be the safe distance of these wires from a control panel
