Eaton N29M28T15A Ventilated Transformer - UL Listed
Part Number: N29M28T15A
Quick Summary
The Eaton N29M28T15A ventilated transformer provides reliable three‑phase voltage conversion for industrial control panels and power distribution enclosures. Engineers often battle overheating, voltage drift, and heat buildup inside compact enclosures, driving maintenance costs and unscheduled downtime. UL Listed safety certification and the K‑13 design address fault tolerance, while a 150°C rise rating and WS38 weather shield support operation in harsh environments. Aluminum windings and an electrostatically shielded construction further reduce EMI, improving equipment life and protection for sensitive drives and controls. Field-adjustable taps (+2.5% and −2.5%) enable precise voltage tuning to match site conditions, delivering reliable performance with minimal installation hassles.

FAQs
Install the transformer in a ventilated enclosure or switchgear rack with proper clearance for airflow. Connect the 208 V primary to the system bus and the 208Y/120 V secondary to the control circuits. Use the field taps to fine-tune voltage as needed and follow the manufacturer’s wiring diagram and safety practices. Ensure the WS38 shield is in place if the installation is exposed to outdoor conditions.
Key specs include 15 kVA, three-phase, 60 Hz, primary 208 V, secondary 208Y/120 V, aluminum windings, electrostatic shield, 150 °C rise, frame 912B, taps of 2 at +2.5% and 4 at −2.5%, UL Listed, WS38 weather shield, and model A catalog notes.
Yes. The transformer features WS38 weather shield and a ventilated design suitable for harsh environments, combined with UL Listed safety compliance to support outdoor or semi-outdoor panel installations.
This unit is UL Listed for electrical safety. The design also supports reliable operation at 60 Hz with a 150 °C rise, and it is built to meet industry standards for rugged industrial use.
EMI reduction from the electrostatic shield and rugged cooling reduce drive noise and heat-related downtime. Field taps simplify voltage tuning, lowering external regulation needs, while aluminum windings reduce material costs. A one-year warranty provides lifecycle protection and predictable maintenance planning.
