Totally enclosed non-ventilated construction protects windings and minimizes dust ingress, reducing maintenance cycles and extending service life in harsh industrial environments. This translates to lower ownership costs and fewer unplanned outages in manufacturing lines and distribution cabinets. The DT-3 design with copper windings delivers high efficiency and robust thermal performance, enabling reliable operation under continuous load and long duty cycles in control rooms and machine cells. With a 30 kVA three-phase rating and a 480 V primary feeding 208Y/120 V secondary, you can power multiple control panels and drive systems from a single, compact unit, simplifying panel design and reducing space requirements in new builds or retrofits. The +5% / -5% taps provide voltage regulation to accommodate modest utility swings, improving equipment performance and protecting connected sensors and drives. Frame 915DN and a 615 lb weight facilitate rack- or cabinet-mounted installations, streamlining field assembly and service access. UL Listed certification confirms safety compliance for industrial environments, while the warranty coverage supports long-term procurement strategies. The 22 in depth, 29 in width, and 32.02 in height footprint fits common electrical enclosures, enabling quick integration with existing power distribution schemes. Copper windings and dry-type cooling enable lower surface temperatures and reduced risk of moisture-related faults in dusty facilities. This transformer is a trusted solution for lean maintenance programs and uptime targets in automotive, packaging, and process industries, where dependable power distribution is critical.

FAQs
Install within a suitable enclosure that accommodates a 915DN frame and the unit’s 22 x 29 x 32 in footprint. Allow clearance for air convection and accessible wiring, connect three-phase 480 V primary to the 208Y/120 V secondary circuit, and utilize the +5% / -5% taps to adjust voltage as needed. Ensure mounting hardware supports the 615 lb weight and follow UL-listed installation guidelines to maintain safety and warranty.
Key specs are 30 kVA, three-phase, primary 480 V, secondary 208Y/120 V, 60 Hz, copper windings, and DT-3 enclosure. These specs enable efficient distribution to multiple control panels with stable voltages under continuous load. The +5% / -5% taps support minor voltage regulation, while the 150°C rise rating indicates robust thermal performance for demanding environments.
Yes. The unit’s totally enclosed non-ventilated design protects windings from dust and moisture, making it well-suited for factory floors, machine rooms, and panel enclosures where cleanliness cannot be guaranteed. UL Listed certification adds safety credibility, and the rugged DT-3 dry-type design supports reliable operation in harsh indoor settings with minimal maintenance.
UL Listed confirms the transformer meets established electrical safety standards for equipment used in industrial environments. It provides assurance to specifiers and electricians that the V48M28T30CUNV has undergone safety testing and is suitable for routine installation in control panels and distribution cabinets when used as designed by Eaton.
The dry-type, totally enclosed design minimizes cooling needs and dust ingress, reducing maintenance frequency and expenses. Copper windings offer high efficiency and low energy losses, contributing to lower operating costs over the life of the unit. With a one-year warranty (or 18 months from shipment) and UL certification, this transformer supports predictable total cost of ownership and steady uptime for manufacturing and distribution applications.
