Which is the neutral pole on a 4-pole Masterpact NW?

Product Line:
Masterpact NW NT

Resolution:
By default, the neutral is the left pole.  It may be ordered as a right-pole neutral and if so the catalog number will have a "B" in position 19 or 20.
The neutral is protected and a neutral current transformer NCT is not required if sensing ground-fault.
