Does SquareD/Schneider Electric make a 3 phase Transformer with a neutral on the primary input side?

Most three phase Transformers have Delta primaries, with no neutral

Product Line:
LV Transformers

Applies to LV Transformers by SquareD/Schneider Electric

Delta Primaries are inherently more stable


SquareD/Schneider Electric provides Wye primary on Delta secondary with center tap Transformers (T151 voltage code). The primary of this unit does not provide a terminal for a neutral. Connecting the primary of a Transformer to the neutral point of a Wye system can cause troublesome neutral currents during times of imbalance.  Generally,  it is best to select a Delta primary for most 3 phase applications, even when connecting to a Wye power system.
