FAQs
Plan for a sturdy, level concrete foundation to support the 2510 lb unit with floor mounting. Ensure clear access for wiring connections (283B) and maintenance, maintain proper ventilation around the NEMA 2 enclosure, and allow space for cable pull and disconnects. Verify 33.5 in depth, 66.18 in height, and 42.18 in width fitment and local clearance codes.
The unit provides 225 kVA/kVA rating, 60 Hz frequency, three-phase operation, 480 V primary, and 208Y/120 V secondary. Voltage regulation is supported by a tap changer at +2.5% / -2.5%, insulation rated to 220 °C, and a 150 °C rise temperature. It features copper windings, a shield for EMI protection, and a 50 dB sound level, suitable for demanding plant environments.
Yes. The N48M28T2216CULS50 complies with DOE 2016 Efficient standards and is UL Listed. Catalog notes reference 10 CFR Part 431 (2016) Efficient, ensuring regulatory alignment for energy performance and safety. These certifications support compliance in facilities pursuing energy-labeling requirements and safety approvals.
Best suited for industrial power distribution needs such as manufacturing floors, data centers, and equipment rooms requiring robust voltage regulation and energy efficiency. With a 480 V to 208Y/120 V output, three-phase configuration, and floor-mount design, it supports critical loads from machine tools to controls and drives while reducing heat in enclosed spaces.
Expect lower maintenance due to copper windings and a rugged NEMA 2 enclosure, with a long service life under continuous operation. Energy efficiency from DOE 2016 performance reduces operating costs, and the electrostatic shield minimizes EMI impacts on nearby automation and sensors, contributing to higher uptime and a favorable return on investment over time.
