Does SquareD/Schneider Electric offer a Non-Ventilated Transformer that is UL rated?

 Issue:
Non Ventilated Transformers

Product Line:
LV Transformers

Environment:
Applies to LV Transformers by SquareD/Schneider Electric

Cause:
UL Ratings for Transformers

Resolution:

Yes and No,
Yes -- for Encapsulated Transformers up to 30kVA three phase and 25 KVA single phase
No -- for Non-Ventilated versions of Ventilated style units. It is not possible to keep the wiring compartment temperature at only a 5 Degrees C rise above a maximum ambient of 40 Degrees C as required for UL. SquareD/Schneider Electric recommends installers use a higher temperature rated cable (above 90?C) when terminating conductors in this style of Non-Ventilated Transformer.
