Eaton X48M28B4516CUNON Harmonic Transformer - DOE2016
Part Number: X48M28B4516CUNON
Quick Summary
Eaton Harmonic mitigating transformer X48M28B4516CUNON provides clean, reliable power conditioning for industrial facilities. In practice, harmonic distortion, voltage sags, and unexpected outages can degrade drives and shorten equipment life, causing costly downtime. This model aligns with DOE 2016 efficiency standards, is UL Listed, and complies with 10 CFR Part 431 efficiency requirements—all housed in a rugged NEMA 2 enclosure with copper windings for durability. The floor-mount, three-phase design supports 480 V delta primary and 208Y/120 V four-wire secondary, while accurate tap settings at +2.5% and -2.5% help maintain voltage under load. By combining energy efficiency with predictable performance, this transformer reduces operating costs and simplifies compliance for industrial automation, data centers, and manufacturing environments.

FAQs
This unit is floor-mounted for indoor use with a NEMA 2 enclosure. It supports a 480 V delta primary and 208Y/120 V four-wire secondary, with a 200X wiring connection and tap options of +2.5% and -2.5%. Ensure adequate clearance for cooling, proper ventilation, and alignment with existing three-phase feeders to minimize voltage drop and thermal buildup.
The design mitigates harmonic currents and voltage distortion, reducing total harmonic distortion (THD) and safeguarding sensitive drives and controls. In practice, this translates to lower overheating risk, improved motor life, and more stable control of programmable logic and motion systems.
Key verifications include DOE 2016 energy efficiency compliance, UL Listing for electrical safety, and 10 CFR Part 431 efficiency alignment. These certifications support regulatory compliance, energy performance disclosures, and a smoother procurement and inspection process for regulated facilities.
Common applications include data centers, manufacturing lines with heavy motor loads, HVAC systems, and automation panels. The 480 V to 208Y/120 V configuration supports standard industrial equipment while the copper windings and robust enclosure handle continuous operation in demanding environments.
Expect energy savings from DOE 2016 efficiency, reduced downtime due to improved power quality, and longer equipment life from lower harmonic stress. The UL listing and robust NEMA 2 enclosure simplify maintenance planning, while the unit’s reliable copper winding design minimizes replacement frequency and service interruptions.
