FAQs
N29M28T45X uses the 914D frame and is a three-phase, 45 kVA transformer with a 208 V primary and 208Y/120 V secondary. It aligns with common enclosure footprints and mounting patterns, simplifying installation in panelboards, switchgear, and automation cabinets. The unit also features taps at +2.5% and -2.5% to accommodate minor supply variations without rewiring.
The N29M28T45X is a K-Factor nonlinear ventilated transformer designed to handle distorted waveforms, reducing overheating risks. Key specs include 50–60 Hz operation, 150 °C rise, 45 kVA rating, aluminum windings, and an electrostatic shield. These features help maintain voltage integrity and limit EMI in systems with variable loads such as VFDs and robotics.
Yes. With a 45 kVA three-phase rating, 208 V primary, and 208Y/120 V secondary, the N29M28T45X provides solid power conditioning for critical loads. Its shielded construction and weather protection (WS39) support reliability in factory floors and data-center peripheral cabinets, while the 914D frame aids fast integration into standard racks or enclosures.
This transformer is UL Listed, indicating compliance with recognized safety standards for electrical equipment. For installations requiring additional certifications such as CE or IP ratings, please consult Eaton datasheets or regional compliance guides, as those specifics are not listed for this model and may vary by region or application.
Expect a maintenance profile aligned with industrial transformer practice: robust aluminum windings, shielded windings for EMI control, and a weather-shielded enclosure. The stated Eaton warranty is one year from installation or eighteen months from shipment, whichever comes first, supporting asset protection and predictable total cost of ownership through reliable performance and reduced downtime.
