Selling Policy 25-000 - Distribution and Control Products and Services
Copper windings deliver low electrical resistance and robust reliability under steady loads, enabling improved efficiency and reduced copper losses in 30 kVA transformers. For industrial automation panels, this means cooler operation and longer service life, even in tight spaces where airflow is limited. The DT-3 dry-type design with a 916AN frame provides a compact footprint suitable for switchgear and distribution rooms. The totally enclosed non-ventilated enclosure minimizes dust ingress and simplifies installation, reducing maintenance and enclosure space requirements in facilities with limited ventilation. Voltage flexibility is built in with taps at +5% FCAN and -5% FCBN, allowing on-site voltage tuning for ±5% variation in primary or secondary loads, ensuring stable downstream voltages for sensitive automation equipment. The 30 kVA three-phase rating supports distribution to panels, motors, and automation circuits, while copper windings and a 80 °C rise rating support reliable operation in diverse ambient conditions. Durability is further enhanced by the DT-3 design and a frame that fits standard footprints, enabling easier retrofit and expansion in existing automation infrastructures. Overall, the V48M28B30CUNV balances performance and footprint, driving installation simplicity, reduced retrofit requirements, and favorable total cost of ownership for power management teams.

FAQs
The V48M28B30CUNV is designed for 480 V three-phase input with a 208Y/120 V secondary output and operates at 60 Hz. It features copper windings, an 80 °C rise rating, and taps (+5% FCAN, -5% FCBN) for on-site voltage adjustment, ensuring stable performance across typical US distribution environments.
Key specs include a 30 kVA rating, three-phase configuration, primary 480 V, secondary 208Y/120 V, 60 Hz frequency, copper windings, a 916AN frame, 80 °C rise, and voltage taps at +5% FCAN and -5% FCBN. It is UL Listed and suited for dry-type distribution in indoor installations.
Yes. With a compact DT-3 dry-type design, the V48M28B30CUNV fits into automation cabinets and control panels. Its 30 kVA rating supports common automation loads, copper windings minimize losses, voltage taps enable regulation for sensitive equipment, and the UL Listed certification provides procurement confidence for panel builders and end users.
The transformer carries UL Listed certification, indicating compliance with recognized safety standards for electrical distribution equipment. This aids regulatory alignment, simplifies procurement approvals, and supports warranty coverage. For international projects, verify regional certifications such as CE or others as required by local codes.
As a dry-type transformer with a totally enclosed non-ventilated enclosure, it offers lower maintenance than liquid-filled units and avoids oil-related concerns. The 30 kVA rating paired with copper windings and a proven frame design reduces lifecycle costs, while a standard warranty (one year from installation or 18 months from shipment) supports predictable total cost of ownership.
