FAQs
To install the N48M28B7516CUSS47-US correctly, confirm the site uses a 480 V delta primary and 208Y/120 V secondary, with a 60 Hz supply. The unit features a CASE C frame, NEMA 3R stainless enclosure, and a 1600 lb footprint. Ensure adequate clearance for ventilation, align with tap changer options, and support mounting on a sturdy floor or rack.
Key efficiency features include DOE 2016 Efficient compliance, copper windings with a nonlinear ventilated design, and an 80 °C temperature rise allowance. Together, these reduce idle losses, heat generation, and cooling load, translating into lower energy costs and improved reliability in continuous operation. The 47 dB sound profile also minimizes acoustic disruption in quiet workspaces.
Yes. The NEMA 3R stainless steel enclosure provides corrosion resistance and weather protection, making it suitable for outdoor and washdown-intense environments. UL Listed status supports compliance in regulated facilities. The robust CASE C frame, copper windings, and 75 kVA rating ensure dependable performance across a wide temperature range, while the 80 °C rise tolerance supports heavy-duty loads.
Certified UL Listed and DOE 2016 Efficient status ensure regulatory alignment for many facilities. The catalog notes reference 10 CFR Part 431 (2016) Efficient, supporting energy reporting requirements. These certifications, combined with rugged stainless enclosure and NEMA 3R designation, simplify approval processes for industrial, data center, and healthcare supply environments where compliance and traceability matter.
Expect a favorable ROI through reduced energy costs, lower cooling requirements, and longer intervals between servicing thanks to copper windings and robust construction. UL listing and DOE efficiency minimize regulatory risk, while the stainless steel enclosure withstands harsh environments. Regular checks on tap changers (2 AT +2.5% FCAN, 4 AT -2.5% FCBN) and periodic insulation reviews keep performance stable and extend service life.
