FAQs
Start with mounting on a rigid panel or channel frame, ensure clearance for airflow around the DT-3 open-core design, then connect primary 480 V lines and secondary 220Y/127 V circuits per the schematic. Verify taps set to the correct FCAN/FCBN positions and confirm copper windings are intact. Finally, perform insulation and continuity checks and follow UL Recognized safety guidelines during commissioning.
The unit is a three-phase, 45 kVA dry-type distribution transformer with a 480 V primary and 220Y/127 V secondary, rated for 60 Hz.
