Feature → Business Impact → Application: The V48M47T75NV uses a totally enclosed non-ventilated (TENV) enclosure that minimizes dust ingress and reduces cooling requirements, extending service life in harsh factory environments and lowering maintenance. Application: ideal for rugged manufacturing floors and outdoor installations where reliability and minimal fan cooling are critical. Feature → Business Impact → Application: With a 75 kVA three-phase rating and a 480 V primary to 480Y/277 V secondary configuration, it supports scalable plant power distribution and reduces the need for multiple smaller transformers. Application: suitable for central distribution rooms and data centers with varied load profiles. Feature → Business Impact → Application: Aluminum windings provide corrosion resistance and lighter weight, improving installation efficiency and long-term durability in damp or corrosive environments. Application: suitable for coastal facilities or plants with aggressive atmospheres. Feature → Business Impact → Application: Tap changes at 2 at +2.5% and 4 at -2.5% allow precise voltage regulation to maintain equipment performance and reduce nuisance trips. Application: essential where supply voltage drifts, motors, and drives require stable input. Feature → Business Impact → Application: Frame 916AN and a compact footprint (23.42 in x 46.58 in x 28.22 in) simplify mounting and clearance planning. Application: fits standard electrical rooms and tight spaces, enabling faster installation and easier retrofits. Feature → Business Impact → Application: 150°C rise rating supports higher continuous operation margins and compliance with design standards for dry-type transformers. Application: ensures reliability under peak load conditions across industrial processes. Feature → Business Impact → Application: UL Listed certification validates compliance to safety standards, speeding procurement and installation. Application: essential in regulated facilities and contractor-led projects where documentation matters.

FAQs
For install, plan on a rigid, vibration-free mounting surface with access to the front panel for taps and connections. Ensure clearances around the 23.42 in depth and 46.58 in height for serviceability. Use a properly rated enclosure and follow NEC/UL guidelines, noting the UL Listed status and DT-3 dry-type design.
Key specs include a 75 kVA rating, three-phase configuration, primary voltage of 480 V, secondary voltage of 480Y/277 V, 60 Hz frequency, and tap change options of 2 at +2.5% and 4 at -2.5%. Aluminum windings and a 150 °C rise rating support robust performance under peak loads.
Yes. The V48M47T75NV is designed for general-purpose distribution with a dry-type, DT-3 enclosure suitable for varied plant loads. Its 480 V to 480Y/277 V output supports motors, drives, and control circuits, while the voltage taps help maintain stable operation across fluctuating supply conditions.
The unit is UL Listed, indicating compliance with recognized safety standards. The DT-3 dry-type design and totally enclosed non-ventilated construction further support reliability and safety in industrial environments, simplifying approvals for regulated facilities and helping ensure consistent procurement documentation.
Maintenance is minimized by the dry-type, TENV enclosure and aluminum windings, reducing cooling needs and corrosion risk. The 75 kVA rating supports centralized distribution, potentially lowering footprint and part counts. A reliable uptime in harsh environments translates to lower operational interruptions and a favorable total cost of ownership over the equipment’s life.
