FAQs
The N48M28T15ZCUEE is a three-phase 60 Hz transformer with a 480 V primary and 208Y/120 V secondary, designed for standard industrial panels. Ensure correct mounting on the 912BZ frame, verify copper windings orientation, and connect taps per the +2.5%/ -2.5% settings to achieve the desired output within tolerance. Use the WS38 weather shield for outdoor or exposed installations and follow UL/TP-1 guidelines during assembly for compliant, safe operation.
Key specs include a 15 kVA VA rating, 60 Hz frequency, three-phase configuration, primary 480 V, secondary 208 Y/120 V, and 150°C rise with 200°C insulation. Taps are +2.5% and -2.5% to fine-tune voltage. Copper windings on a 912BZ frame ensure efficient heat transfer and reliability under non-linear loading conditions typical of modern control systems.
Yes, with the WS38 weather shield option and electrostatically shielded construction, the N48M28T15ZCUEE is suited for outdoor or semi-exposed installations. Its NEMA TP-1 efficient design supports rugged environments, while UL Listed certification provides assurance for outdoor electrical rooms, helping maintain reliability under variable temperatures and humidity.
This transformer is UL Listed and NEMA TP-1 compliant, ensuring safety and energy efficiency for industrial power distribution. The combination of UL certification and NEMA TP-1 compliance simplifies procurement for regulated facilities, supports installation under standard industry practices, and reduces compliance risk during audits.
Maintenance is typically limited to periodic inspection of connections, cooling paths, and insulation integrity given the copper windings and ventilated design. The 15 kVA rating supports scalable growth, while low heat generation via K-Factor design reduces cooling loads. Over time, reliable operation minimizes downtime, enhances asset availability, and lowers total cost of ownership in manufacturing and distribution centers.
