What is the maximum ambient temperature that a Transformer can be installed in?

Issue:
Ventilation and cooling is an important issue in the installation and operation of Transformers

Product Line:
LV Transformers

Environment:
Applies to all Low Voltage (LV) Transformers by SquareD/Schneider Electric

Cause:
Excessive heat is destructive to Transformers

Resolution:
The 24 hour average ambient temperature is 30 degrees C. If the Transformer ambient temperature reached 40 degrees C for 12 hours then the other 12 hours must not exceed 20 degrees C to average at 30 degrees C. A custom Transformer can be manufactured for up to 65 degrees C ambient. Contact the local Field Office for assistance/ quote.
