The holding contact for autotransformer. What is the need? That part is not clear, as the autotransformer get disconnected with the maincontactor NC and star contactor holding contact.

Sir, please reply.... How holding connection of T/R contactor work when timer change the NC ponit to NO point? If it can't work after timer change NC to NO, then why we used this holding connection of T/R contactor?
Bro what is use of transformer contactor (tr)NC?i think that is not necessary in transformer contactor series. Actually this NC working as a holding circuit, Without NC also circuit working properly, answer me
Ya .. it will work even without transformer contactor but T/R No gives some more time supply to main transformer contact. So chane over of motor from transformer to Main contact is smooth.
See breaking sequence of contactors... Its in milli seconds but matters.. first star contactor breaks.. than main contactor makes.. than transformer contactor breaks.. so at every point motor is connected with power supply. Now think of alternate way.. there you will find discontinued supply for duration of break of transformer contact and make of main contactor.
Auxiliary contactor NC may be OFF indication Lamp connect ON indication Lamp may be connected by Main contactor (Run mode) Trip lamp may be OLR relay NO connect
Ckt of power and control wiring explained very nicely.
