The photo of the three phase auto 77 KVA transformer, part number 18703N is shown below. This is ideal for 540/480 to 440 step down applications. The transformer is housed inside an indoor enclosure. Auto transformers are much cheaper than isolation transformers. A comparable isolation transformer will be 5 times bigger in size with higher cost.
