FAQs
The X48M28T3016CUTHR is a three-phase transformer rated for 30 kVA with a 480 V primary and 208Y/120 V secondary, designed for floor mounting in indoor environments. It uses copper windings, a B48MD28 wiring connection, and fits within a footprint of roughly 24.9 in wide by 21.1 in deep and 36.9 in tall, enabling straightforward integration into standard electrical rooms.
This transformer is an energy-efficient harmonic mitigating design, compliant with DOE 2016 and 10 CFR 431, engineered to reduce harmonic distortion and improve overall power quality. Expect measurable improvements in THD, reduced overheating risk for sensitive equipment, and enhanced efficiency in facilities with nonlinear loads such as VFDs and non-linear power supplies.
Yes. The unit is UL Listed and engineered to meet DOE 2016 efficiency requirements, with additional compliance under 10 CFR Part 431. This combination supports regulatory approvals, safer operation, and energy-code alignment for industrial facilities and data centers.
Plan a floor-mounted installation in a protected indoor space (NEMA 2 enclosure) with dimensions around 24.9 in W x 21.1 in D x 36.9 in H. Ensure adequate clearance for cooling and maintenance, provide proper bus connections using the B48MD28 wiring, and account for voltage regulation needs via the +2.5% / -2.5% tap settings to accommodate supply variability.
With copper windings, an electrostatic shield option, and a design optimized for energy efficiency, the X48M28T3016CUTHR reduces energy losses and maintenance costs over its life. UL listing plus DOE/DoE compliance simplifies audits, while its robust enclosure and floor-mount compatibility minimize installation time and downtime, delivering measurable total cost of ownership benefits.
