Schneider EXN45T3HCU – Frequently Asked Questions

1) Will the Schneider EXN T3 transformer give me 120V single-phase circuits off a 480V service?
Yes. The EXN T3 takes a 480V delta primary and puts out 208Y/120V, so you get 208V three-phase between phases and 120V line-to-neutral for receptacle and lighting branch circuits. It is a 3-phase dry-type unit built for low voltage distribution at 60 Hz.
2) What kVA sizes does the Schneider EXN T3 high-capacity transformer come in?
Two sizes: 45 kVA (EXN45T3HCU) and 75 kVA (EXN75T3HCU). Both are the same 480V delta to 208Y/120V copper-wound dry transformer, so pick by connected load, not by any difference in voltage or configuration.
3) Does this Schneider transformer meet DOE 2016 efficiency requirements?
It is identified as a DOE 2016 energy efficient dry transformer, which is the federal efficiency standard applied to distribution transformers in new commercial work. If your project spec or utility rebate program calls out DOE 2016, this line is the one to pull.
4) Does this transformer need forced-air cooling or clearance for fans?
No fans. Cooling is natural convection, so there is no blower to power, maintain, or fail, and no forced-air noise. Plan the install for free air movement around the enclosure and keep it out of a sealed closet with no ventilation.
5) Is the Schneider EXN T3 a copper-wound transformer or aluminum?
Copper. That matters on a retrofit where the spec or the drawing calls for copper windings and an aluminum-wound unit would get rejected at inspection or submittal review.
6) What ambient temperature can the EXN T3 transformer be installed in?
It is rated for operation at 40 degrees C ambient with a 30 degree C average ambient. A mechanical room or electrical room that runs hot through the day is fine as long as the average stays around 30 C and peaks do not exceed 40 C.
7) Is this the same as a Square D transformer?
Yes, the EXN T3 is part of the Square D range under Schneider Electric. If your existing gear, panel schedules, or facility standard is Square D, this fits that same family. Units are made in Mexico and carry full traceability.
8) Does the EXN T3 dry transformer meet RoHS and REACH for a green building submittal?
It carries Schneider's Green Premium status, is EU RoHS compliant, and is free of REACH Substances of Very High Concern above threshold. It is also mercury free and free of toxic heavy metals, and the environmental product declaration reference is ENVPEP1604027_V2 for LEED or sustainability documentation. Packaging is recycled cardboard with no single-use plastic.
9) Will this transformer work on a 50 Hz system?
No. The EXN T3 is specified at 60 Hz, which is North American utility frequency. For a 50 Hz export or international project you need a transformer rated for that frequency.
10) Can the EXN T3 handle surges on the 480V side?
The rated impulse withstand voltage is 10 kV, which covers transient and switching surges typical of a 480V feeder. It is not a substitute for a surge protective device on sensitive downstream loads, but the windings themselves are rated to 10 kV impulse.
11) Are the windings on this Schneider dry transformer field serviceable?
No. The EXN T3 is listed as non-serviceable, so treat it as a replace-not-repair unit. For a facility standardizing on these, that argues for planning around the 25-year average life duration rather than budgeting for winding repair.
