That sounds as your concern is that the short circuit current will be much greater with 3-phase AC power, than with single phase or DC.
Yes, indeed, it is normal to try and keep the AC power and control separate as far as is practically possible. But you dont have to split into separate control cabinets.
You "merely" have to bring down the short circuit current on the control side by some means. That is typically done by a control transformer for AC or a 3-phase-to-24DC for DC.
Over here you also are not allowed to open a panel if it has more than 48V and you dont have a full electricians education.
What you describe sounds to me to be an extra measure. I can see that it is certainly safer. But do companies really allow non-electricians to dabble with control panels, even if it is low-voltage ?
