FAQs

To install, mount on a floor-ready base per the enclosure’s NEMA 3R rating and connect to a 480 V primary with a 208Y/120 V secondary system. Verify clearances, provide appropriate grounding, and follow local electrical codes. Use compatible protective devices and perform voltage checks after tap-changer adjustments to ensure stable output. Consult Eaton installation guides for sequencing and lockout-tagout procedures.
Key performance specs include a 300 kVA rating, 60 Hz operation, 480 V primary, 208Y/120 V secondary, and a 150 °C insulation rise with copper windings. DOE2016 efficient rating supports lower no-load and load losses. Voltage regulation varies with load, but the +2 / -4 taps help maintain secondary voltage. Sound level is documented to NEMA ST-20 standards.
Yes, the N48M28T3316QCU is well-suited for data centers, manufacturing lines, and large-scale HVAC loads where stable voltage and compact footprint matter. Its 32-inch depth, 66-inch height, and 50.5-inch width fit utility rooms with limited space when floor-mounted. The transformer’s rugged enclosure and copper windings provide reliability under fluctuating loads common in industrial environments.
This transformer carries UL Listed certification and DOE2016 Efficient compliance, with a 10 CFR Part 431 (2016) Efficient catalog note reinforcing energy performance. These certifications simplify procurement, reduce regulatory risk, and support energy-management programs. Additional standards include 60 Hz operation, NEMA 3R enclosure, and a copper-wound design that meets reliability and safety expectations for industrial power systems.
Routine maintenance for this dry-type transformer centers on periodic inspection of enclosure integrity, cooling pathways, winding insulation and tap-changer operation. The 150 °C rise rating and copper windings yield robust durability, reducing unplanned downtime. ROI is driven by energy savings under DOE2016, longer service intervals, and simplified compliance, which lower total cost of ownership over the equipment’s life.
