FAQs
Installation should account for a 3-phase, 60 Hz system with a 480 V delta input and a 208Y/120 V secondary. The unit uses a CASE C frame and a NEMA 3R enclosure, enabling outdoor placement with correct clearance for ventilation. Ensure adequate space for cooling, secure mounting on a solid pad, and proper connection to distribution equipment rated for the dual-tap voltage options (+/− taps) to match system voltage under load.
The transformer delivers 75 kVA with 60 Hz operation, 480 V delta primary, and 208Y/120 V secondary. DOE2016 Efficient and UL Listed ratings support regulatory compliance and energy savings. With a sound level of 47 dB and a 115 °C rise, it balances quiet operation and robust thermal performance for continuous-duty applications, improving uptime and reducing cooling energy needs.
Yes. The NEMA 3R enclosure combined with aluminum coil construction and 220 °C insulation supports outdoor and harsh indoor environments. Its rugged CASE C frame and UL Listed certification provide assurance for outdoor installations, while the ventilated design helps manage heat in energy-intensive facilities such as data centers and production lines.
The unit is UL Listed and conforms to DOE2016 Efficient standards, with catalog notes referencing 10 CFR Part 431 (2016) Efficient. These certifications assure compliance with safety and energy-performance regulations, reducing regulatory risk, qualifying for energy incentives, and helping meet corporate sustainability goals in procurement specifications.
ROI benefits come from DOE 2016 efficiency reducing energy consumption and cooling loads, along with improved reliability from robust construction. Maintenance requirements focus on ensuring ventilation remains unobstructed, periodic inspection of terminals, and monitoring for typical wear on taps (2 AT +2.5% FCAN and 4 AT −2.5% FCBN) to maintain voltage regulation and performance over time.
