Some specifications may dictate the winding material on Transformers
Applies to Ventilated and Non Ventilated Transformers by SquareD/Schneider Electric
Transformers may utilize one of two possible coil winding materials, aluminum or copper
If the catalog number of a SquareD/Schneider Electric Transformer, built in style D, E or F enclosures (Ventilated and Non-Ventilated) does not have ``CU`` as part of the suffix behind the letter that denotes the temperature rise of the Transformer (an ``H`` "HF" or``HB``,) the windings are standard aluminum.
This is done at SquareD/Schneider Electric`s discretion to make the most competitive, high quality product available in the market. If part of the suffix does have ``CU`` in it, then the windings are copper. The only exception to this is in SquareD/Schneider Electric Sealed Resin Epoxy Encapsulated Transformer offering (enclosure styles A, B, or C,) which are only offered with copper windings.
