How does one find out the heat generated by low voltage dry type Transformers?

How can we help you today?

Issue:
Transformer heat generation data

Product Line:
LV Transformers

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

Cause:
Heat output data is often needed for ventilation, airflow and air conditioning calculations

Resolution:
Heat generated by a Transformer is a function of how it is loaded. The customary request is for the BTU/hr output at the Transformer`s full load. To obtain this data, please contact Product Marketing who will provide the data on a catalog number by catalog number basis. This data, (which is subject to change without notice when changes are made to the Transformer`s design by engineering, for common energy efficient low voltage Transformers), is also found in Data Bulletin 7400DB0702 (Energy Efficient Transformers Technical Data).
