The solar duty rating and solid construction provide reliable power isolation for demanding environments, reducing nuisance outages and improving overall system uptime. This translates to lower maintenance costs and higher productivity in solar-integrated facilities, making it well-suited for industrial plants, data centers, and retrofit projects where consistent voltage is critical. DOE2016 Efficient performance and UL Listed safety certifications directly impact procurement and regulatory compliance, delivering measurable energy savings and risk mitigation. The transformer’s 300 kVA capacity, three-phase configuration, and 480 V delta primary with a 208Y/120 V secondary support scalable distribution from main feeds to localized panelboards, enabling flexible design in manufacturing lines and service entrances. Aluminum windings and 60 Hz operation contribute to durability, corrosion resistance, and reliable performance in hot, dusty environments, while the NEMA 2 enclosure and FR945 frame simplify installation in standard electrical rooms. Tap changers at 2 AT +2.5% FCAN and 4 AT -2.5% FCBN offer voltage adaptability without compromising reliability, reducing voltage drop downstream and protecting sensitive loads. The unit’s 150°C rise and 220°C insulation specification deliver resilience under peak loading, supporting longer service life in high-demand operations. Its weight of 2277 lb, dimensions, and WS62 weather protection facilitate on-site planning, rigging, and mounting in conformance with space and safety requirements. Overall, this transformer integrates seamlessly with energy management strategies, enabling better return on investment through improved efficiency, reduced energy losses, and easier regulatory adherence.

FAQs
This transformer is designed for indoor industrial spaces such as electrical rooms, service bays, and retrofit installations where rugged protection is required. The NEMA 2 enclosure provides dust and some moisture resistance, while the FR945 frame supports stable mounting and long service life in demanding environments. Heavyweight construction also supports safer handling during installation.
The unit delivers 300 kVA at 60 Hz, three-phase, with a 480 V delta primary and a 208Y/120 V secondary. Aluminum windings enable high thermal conductivity and corrosion resistance. This configuration supports scalable distribution from the main feeder to local panels, reducing voltage drop and improving load performance for industrial loads and solar-driven applications.
DOE 2016 efficiency requirements reduce core and copper losses, translating to lower no-load and load losses over the transformer's life. For facilities with variable solar and industrial loads, this yields meaningful energy savings, lowers utility bills, and supports sustainability goals while maintaining compliance with energy regulations.
Yes, the V48M28T3316PV is UL Listed, and it also complies with DOE2016 Efficient and 10 CFR Part 431 Efficient standards. These certifications enhance procurement eligibility, ensure safety, and demonstrate adherence to energy efficiency regulations essential for regulated industries and public sector projects.
