FAQs
Plan for a three-phase, 480 V input with a 208Y/120 V output, allowing space for the 82-100 lb transformer weight range depending on mounting. Ensure adequate clearance for ventilation, support for the 916A frame, and access to the taps (+2.5% and -2.5%) during commissioning. Confirm UL Listed and NEMA TP-1 compliant installation practices for regulatory alignment.
Copper windings provide superior electrical conductivity and heat dissipation, reducing winding resistance losses. The 150°C rise rating establishes a higher thermal margin, enabling sustained loading with less insulation stress and longer service life in demanding environments such as packaging lines and machine centers.
Yes. The N48M28T50CUEE is a three-phase transformer designed for a 480 V primary and a 208Y/120 V secondary, compatible with standard industrial power distribution schemes and control panels, with 60 Hz frequency and copper windings to ensure stable voltage transformation.
This unit is UL Listed and NEMA TP-1 compliant, with catalog notes indicating NEMA TP-1 efficiency. These certifications support regulatory approvals, safer operation, and energy-efficient performance in commercial and industrial facilities.
With a low heat profile, electronic shielding, and weather protection (WS19), maintenance intervals are extended and downtime reduced. The robust insulation and copper windings minimize derating and unexpected failures, delivering improved uptime and lower total cost of ownership across production lines.
