Eaton V48M28T37NV Transformer - UL Listed, DT-3 Dry Type
Part Number: V48M28T37NV
Quick Summary
Eaton V48M28T37NV Transformer is a rugged dry-type power distribution unit engineered for industrial facilities. When uptime matters, issues like enclosure exposure, overheating, and costly maintenance can throttle productivity. This unit carries UL Listed safety certification and the DT-3 design, plus a three-phase 37.5 kVA rating with aluminum windings for reliability. The totally enclosed non-ventilated enclosure minimizes dust ingress and venting requirements, reducing service frequency and risk. With 480 V primary and 208Y/120 V secondary, it supports common facility voltages while maintaining compact dimensions. In short, it delivers predictable performance, scalable capacity, and a clear path to lower total cost of ownership for control rooms, panels, and machine lines.

FAQs
Plan for a medium-duty indoor installation with a dedicated footprint of about 22 in depth, 29 in width, and 32.02 in height. The unit weighs 485 lb, so include appropriate lifting and anchoring. Use the DT-3 dry-type, totally enclosed design in spaces where vented transformers are undesirable, and ensure adequate clearance for access to taps (+2.5% / -2.5%) and service panels.
This transformer provides 2 taps at +2.5% FCAN and 4 taps at -2.5% FCBN. Use these taps to compensate for voltage drop along feeders or slight utility fluctuations. Start from nominal 480 V primary and adjust toward +2.5% or -2.5% as measured at the secondary to maintain 208Y/120 V loads within tolerance.
Yes. It uses a totally enclosed non-ventilated DT-3 design with aluminum windings and a 150 °C rise profile, ensuring safe operation in challenging environments with dust, humidity, or moderate heat, while reducing maintenance needs compared with vented oil-filled units.
The unit is UL Listed, reflecting recognized safety compliance. Warranty details follow Eaton’s policy 25-000, providing one year from installation or eighteen months from shipment, whichever occurs first, for protection against defects.
Typical uses include power distribution for control panels, machine tools, and distribution cabinets in manufacturing and packaging lines. Benefits include improved uptime, voltage regulation at critical loads, and reduced maintenance with a compact, durable, dry-type enclosure, contributing to lower total cost of ownership over the asset lifecycle.
