FAQs
The N48D28B1516CU is designed for floor or wall mounting in upright orientation, with an indoor NEMA 2 enclosure. This supports compact electrical room layouts and vertical installation in control panels, MCCs, or switchgear housings, helping to optimize space and simplify wire routing in automation environments.
Key specs include a 15 kVA three-phase rating, primary 480 V, secondary 208Y/120 V, 60 Hz operation, 80 °C rise, K-Factor 13, copper windings, and NEMA 2 enclosure. It also features an electrostatic shield, WS58 weather shield, and 2 at +2.5% / 2 at -2.5% taps for voltage adjustment.
Yes. The transformer is DOE 2016 Efficient and UL Listed, providing energy savings benefits and verified electrical safety. These certifications support compliance with energy-use and safety standards in many industries, reducing regulatory risk during procurement and installation.
Ideal for control panels, automation cabinets, MCCs, and power distribution in manufacturing and process environments. Its three-phase 15 kVA rating, voltage conversion, and harmonic-reducing K-Factor 13 make it suitable for equipment with non-linear loads, data centers, and mixed-use electrical rooms where reliability and efficiency are priorities.
Expect lower operating costs due to DOE 2016 efficiency and reduced harmonic losses from K-Factor 13. Copper windings and robust insulation improve longevity, while the electrostatic shield and WS58 shield provide protection against EMI and environmental contaminants. Routine checks for enclosure integrity, tap compatibility, and load balance will help maximize ROI and uptime.
