TP - 3P switching no N
TPN - 3P switching with un-protective N (no problem unless the motor winding body to the metal) 😀 - other machines/electronic devices (grounded might get affected otherwise)
TPNY - Many factories / countries don't allow TPN because of the above reason. Hence independent switching of N is done along with isolation with ground.

We are in the process of designing a system that alarms whenever neutral line is grounded (for 3P motors), work is still in progress.
