FAQs
Yes. The transformer is designed for 480 V primary and 208Y/120 V secondary in a three-phase configuration, with wiring connection 283B specified to ensure proper termination and code compliance. Its NEMA 2 enclosure supports indoor installation with floor mounting, making it suitable for plant floor or equipment room deployments.
Key specs include 60 Hz operation, 225 kVA rating, 480 V primary to 208Y/120 V secondary, and a 150 °C rise. The unit also features a 52 dB sound level and K-Factor 13. These figures influence load handling, thermal performance, noise, and harmonic resilience in demanding production environments.
Yes. The N48M28T2216CULS52 meets DOE 2016 efficiency requirements and is UL Listed, with additional compliance notes for 10 CFR Part 431 (2016) Efficient. This combination supports regulatory alignment, energy savings, and safer operation in industrial facilities.
The electrostatic shield minimizes capacitive coupling between windings, reducing common-mode EMI and noise transfer to connected equipment. This results in cleaner power delivery, improved performance of sensitive drives and controls, and greater resilience to harmonics typical in modern automation systems.
Dimensions are 66.18 in high, 42.18 in wide, 33.5 in deep with a 2670 lb weight. Floor mounting and a copper-winding, shielded design simplify service access. Regular checks should focus on winding insulation, enclosure integrity, tap settings, and wiring connections (283B) to maintain peak performance and reliability.
