Eaton V48M28F45NV Transformer - DT-3 Dry Type UL Listed
Part Number: V48M28F45NV
Quick Summary
Eaton V48M28F45NV transformer powers dry-type distribution for industrial facilities, delivering reliable three-phase 45 kVA capacity. Engineers often wrestle with space constraints, ventilation needs, and maintenance costs when deploying transformers. UL Listed certification accompanies the DT-3 dry-type design, helping you meet electrical codes with safer installation. Compact footprint and aluminum windings reduce material costs and cooling requirements, while taps at +2.5% and -2.5% enable voltage regulation without external gear. This compatibility translates to lower downtime, easier service, and a longer asset life across manufacturing lines, data centers, and control panels. For procurement teams, UL Listing and Eaton warranty support supplier qualification and service planning, delivering predictable performance and reduced risk.

Selling Policy 25-000 - Distribution and Control Products and Services
DT-3 dry-type design delivers safer installation and a compact footprint, reducing enclosure cooling requirements and enabling easier wiring in panel boards. Business impact: improved reliability and lower total installed cost. Application: control panels, motor control centers, and distribution boards in manufacturing facilities. The totally enclosed non-ventilated construction allows operation in dusty or humid environments without external cooling, lowering maintenance intervals and failure risk. Application: plants with challenging ambient conditions, outdoor equipment, or rugged factory floors. Aluminum windings reduce weight and corrosion susceptibility, easing field installation and extending service life, while maintaining robust electrical performance under hot plant conditions. Tap changes, two at +2.5% FCAN and four at -2.5% FCBN, provide voltage regulation without external autotransformers. Business value: steady voltage, reduced downstream equipment stress, and simplified commissioning. Compatibility with 480 V primary and 208Y/120 V secondary supports common industrial feeders and panel boards. Warranty supports risk mitigation and asset protection, while the dry-type design minimizes explosive dust risks and simplifies maintenance planning. This solution suits data centers, processing plants, and automation-heavy facilities seeking reliable distribution with predictable lifecycle costs.

FAQs
Key considerations include ensuring ample floor space for a 28.22 in width by 32.02 in height footprint and securing the frame in a vibration-free location. The unit’s 823 lb weight requires appropriate lifting equipment and anchor points. Because it is a totally enclosed non-ventilated design, plan for adequate clearance for cable entry, taps at +2.5% FCAN and 4 at -2.5% FCBN, and compliance with UL Listed installation practices.
This transformer provides a 45 kVA rating, three-phase configuration, 60 Hz frequency, primary 480 V, and secondary 208Y/120 V. It uses aluminum windings, a DT-3 design, and a 115 °C rise. The frame is 916AN, with taps for voltage regulation (+2.5% and -2.5%). It is UL Listed and rated for operation in a dry-type environment, suitable for industrial power distribution.
Yes. The DT-3 dry-type design and compact 916AN frame support integration into dense control panels and MCCs. The 480 V to 208Y/120 V secondary voltages align with common control circuits, and the aluminum windings offer lower weight and installation ease. The unit’s UL Listed status helps with code compliance during panel fabrication and integration into existing automation architectures.
The V48M28F45NV is UL Listed, confirming compliance with recognized safety standards for electrical equipment. While other certifications such as CE or IP ratings are not listed in the provided data, UL Listing provides confidence for North American installations. The product is designed as a totally enclosed non-ventilated transformer to meet typical industrial safety requirements.
Maintenance impact is reduced by the dry-type, totally enclosed design which minimizes cooling requirements and dust ingress. The 45 kVA capacity supports scalable power distribution with voltage taps that simplify on-site regulation, reducing the need for external regulators. Over time, this translates to lower maintenance downtime, predictable lifecycle costs, and a favorable return on investment for plants needing reliable, compact distribution transformers.
