FAQs
The model is designed for indoor floor mounting in a NEMA 1 enclosure, requiring appropriate clearance, level support, and vibration control. With a footprint of 64 in by 44.25 in and a height of 80.25 in, ensure safe access for maintenance, compliant service clearances, and compatibility with existing distribution panels. Include proper grounding and adherence to manufacturer installation guidelines to optimize cooling, accessibility, and safety.
Key specifications include a 500 kVA three‑phase rating, 480 V primary, 208Y/120 V secondary, and 60 Hz. Tap settings include +2 at 2.5% FCAN and −4 at 2.5% FCBN. Copper windings, 80 °C rise, and NEMA 1 enclosure support reliability in standard indoor environments. Verify UL Listing, DOE 2016 Efficient compliance, and alignment with your facility’s harmonic profile and protection schemes.
Yes. The N48M28B5516QCU adheres to DOE 2016 Efficient guidelines and 10 CFR Part 431 requirements, ensuring energy‑efficient performance. It carries UL Listing for added safety assurance. Compliance supports ongoing regulatory programs and can help qualify for energy‑benchmarking and efficiency incentives in many industrial facilities.
It is well suited for general purpose power distribution in both data centers and manufacturing environments due to its 500 kVA rating, robust copper windings, and precise voltage regulation via taps. For high harmonic loads, its K‑Factor 13 design provides resilience, while NEMA 1 indoor protection and floor mounting simplify integration with existing infrastructure.
Plan routine inspections of cooling paths, insulation integrity (220 °C rating), and enclosure sealing to preserve NEMA 1 protection. Copper windings offer longevity with proper thermal management. Regular thermal scans, insulation tests, and mechanical checks help maintain efficiency and prevent unplanned downtime, supporting a favorable total cost of ownership for industrial power distribution.
