a Actual taps may vary based on volts/turn ratio.
b Wall designations for units having standard features.
c Ventilated transformers drip shields are UL listed for
outdoor use.
d Encapsulated transformers are UL listed for indoor/
outdoor use.
If used on unbalanced loads, these auto transformers will
need to be used on a 4-wire system with the supply
neutral connected to the transformer. If used on motor
loads, then they may be used on a 3-wire system without
a neutral or fourth wire. Review in NEC 450-4 and 450-5.
Items marked floor and wall can be wall mounted
with optional wall bracket that may be identified
with “W” suffix on catalog number. Wall mounting
brackets will not be available for Series J 75kVA with
copper winding options. See pages 8-8 and 8-27 for
details.
