Open-core, ventilated design provides efficient cooling and easy inspection, enabling faster maintenance and reduced thermal limits under heavy loads. The DT-3 configuration with a 912C frame enhances mechanical compatibility with standard distribution panels, simplifying retrofit projects and field installations. Voltage regulation is achieved through selective taps, including two taps at +2.5% FCAN and four at -2.5% FCBN, enabling precise secondary voltage control and improved motor starting performance in fluctuating supply conditions. Aluminum windings offer robust thermal performance and corrosion resistance, extending service life in demanding environments while maintaining low weight for a unit of this size. The 60 Hz, three-phase layout ensures balanced loading and predictable vibration characteristics, supporting consistent power delivery to motors, drives, and control circuits. A 45 kVA rating aligns with typical plant feeder requirements, while the 912C frame and open-type core simplify installation and future servicing. UL Recognized certification provides safety assurance, and Eaton’s warranty policy adds financial protection against defects, delivering a compelling total-cost-of-ownership proposition for power-management projects.

FAQs
Yes. The V48M28T45ZZ is designed for a 480 V primary and a 208Y/120 V secondary in three-phase, 60 Hz systems. It uses the DT-3 open-core design with a 912C frame and supports on-site voltage adjustments via taps, facilitating proper voltage delivery to downstream equipment in switchgear and control panels.
The transformer includes two taps at +2.5% FCAN and four taps at -2.5% FCBN. These taps let you fine-tune the secondary voltage to counteract line drop or load variation, maintaining stability for sensitive motors, drives, and controls without overhauling feeders or wiring.
This 45 kVA, three-phase transformer is ideal for general power distribution in manufacturing, processing, and machine-automation environments. It steps down 480 V feeders to 208Y/120 V for control panels, MCCs, and auxiliary equipment, while providing reliable duty and compact installation within standard switchgear footprints.
The V48M28T45ZZ carries UL Recognized certification, signaling compliance with established safety standards for electrical components. The open-core, dry-type design reduces oil-hazard risks, and the aluminum windings plus DT-3 construction support durable, maintenance-friendly operation in industrial facilities.
Eaton provides a warranty under policy 25-000: one year from installation or eighteen months from shipment, whichever comes first. For maintenance, the open-type core and coil assembly design facilitates inspection, filter-free cooling, and straightforward access for routine checks, reducing downtime and service costs.
