FAQs
For best results, plan for a three-phase 480 V input with a 220Y/127 V secondary, mount on the floor, and place the unit within a clean, ventilated area. The NEMA 2 enclosure provides protection against dust and moisture, while the 283B wiring connection supports standard Eaton-compatible terminations. Include space for service access and thermal sensor monitoring to maximize uptime.
The transformer is designed to meet DOE 2016 efficient standards, featuring copper windings, optimized core losses, and insulation rated to 220 °C. These factors collectively reduce no-load and load losses, delivering meaningful energy savings across continuous operation in manufacturing, automation, and distribution applications.
Yes. With a 225 kVA three-phase rating, 480 V input and 220Y/127 V secondary, plus a shielded coil design and thermal sensor, the N48M31T2216TCU is positioned for reliable uptime in critical power distribution. UL listing adds a safety margin, while its robust enclosure and cooling characteristics support continuous operation in data centers and automated facilities.
The unit is UL Listed and DOE 2016 compliant, with a NEMA 2 enclosure for durable protection in industrial environments. Catalog notes reference 10 CFR Part 431 (2016) Efficient, and the design includes K-Factor 13, electrostatic shielding, and thermal sensing for safety and compliance in regulated installations.
Key ROI drivers include the thermal sensor for proactive fault detection, the electrostatic shield for reduced insulation stress, and the copper windings with high-temperature insulation for extended life. Routine checks should monitor coil temperature, enclosure integrity, and wiring connections (283B), ensuring long service intervals and minimized downtime in high-load panels.
