Neutral protection dial settings

Product Line:
Circuit Breakers

Dial settings
4P 3D = Neutral protection is turned off
3P N/2 = Neutral conductor capacity is half that of the line conductors
4P 4D = Neutral conductor capacity is the same as that of the line conductors

1.6N (Neutral conductor capacity is 1.6x that of the line conductors) is also available, but only on 3p breakers.
