The DT-3 Totally Enclosed Non-Ventilated design provides protection against dust, moisture, and ambient contaminants, reducing maintenance cycles and improving uptime in harsh industrial environments. Business impact: longer service intervals and lower operating costs; Application: manufacturing floors, processing plants, and outdoor enclosures. Copper windings deliver higher conductivity and efficiency, cutting resistive losses and improving overall operation cost. Application: continuous process loads, motor controls, and feeder circuits. The 30 kVA three-phase rating with a 480 V primary and 230 V secondary enables straightforward step-down distribution for panels and machine controls, reducing wiring complexity and footprint. Tap adjustments (+5% FCAN and -5% FCBN) offer voltage regulation to accommodate supply fluctuations common in heavy industry, supporting stable equipment operation. Installation in a compact 914DN frame with a durable exterior minimizes space requirements in tight switchgear rooms. The 150 °C rise rating supports reliable operation in elevated ambient temperatures, extending insulation life and reducing HVAC demands. UL Listed certification ensures compliance with safety standards, while the Eaton warranty provides protection against manufacturing defects for product reliability. With a dry-type construction and enclosed design, this transformer reduces maintenance exposure and improves safety for technicians during installation and servicing. Compatibility with standard distribution gear and a weight of 572 lb aids in planning, rigging, and fixed mounting in new or retrofit projects, delivering predictable integration into existing electrical architectures and control cabinets.

FAQs
The V48M23T30CUNV is a dry-type, three-phase distribution transformer rated at 30 kVA with a 480 V primary and 230 V secondary. Its totally enclosed non-ventilated DT-3 design makes it suitable for industrial switchgear rooms, machine rooms, and other spaces with limited ventilation. It supports straightforward mounting on standard bases and works well in spaces with dust or humidity exposure due to rugged enclosure protection.
This transformer uses copper windings to minimize resistive losses and improve efficiency under continuous load. It offers voltage regulation via taps at +5% FCAN and -5% FCBN, enabling better compensation for supply or load variations. Its 60 Hz, 480 V to 230 V configuration supports reliable operation for control panels, motors, and auxiliary systems with tight voltage requirements.
Yes. The unit is UL Listed, indicating compliance with established electrical safety standards for industrial equipment. This certification supports safer installation in commercial and industrial facilities. Additional considerations include compliance with Eaton warranty policy terms (one year from installation or 18 months from shipment) and proper installation in accordance with applicable electrical codes.
The enclosed non-ventilated design reduces exposure to dust and moisture, lowering maintenance frequency and extending service life in harsh environments. Copper windings improve efficiency, contributing to lower operating costs over time. The compact DT-3 footprint facilitates faster installation, fewer enclosure modifications, and predictable downtime planning for production lines.
The transformer uses a 914DN frame with external dimensions of roughly 22 inches in length, 29 inches in width, and 39.18 inches in height, and it weighs about 572 pounds. These specs support planning for hoisting, anchoring, and adequate clearance for cooling and access in panels, switchgear, or equipment rooms.
