Eaton Specification Sheet - RV48M28T4516CUPB
The RV48M28T4516CUPB is a 45 kVA three-phase dry-type transformer with a 480 V delta primary and 208Y/120 V secondary, designed to deliver reliable power distribution in industrial control applications. The copper windings and 220 °C insulation offer robust thermal performance, while the ventilated design supports higher loading with reduced heat buildup, translating to longer service life and lower cooling costs in machine cells and automation cabinets. An integrated MCCB (JGE3160FAGC) and a primary shield option improve protection and EMI performance, enabling simpler cabinet layouts and faster commissioning. With a 2 at +2.5% and 4 at -2.5% tap arrangement and a 60 Hz rating, it accommodates voltage variations common in manufacturing lines. The NEMA 2 enclosure, FR940SD frame, and 521 lb weight emphasize ruggedness and installation flexibility for floor- or wall-mounted setups. This solution reduces component count, simplifies maintenance, and supports compliant, sustainable power distribution in modern plants.

FAQs
Mounting the RV48M28T4516CUPB requires a floor- or wall-mounted enclosure in a clean, ventilated area. It weighs about 521 lb and fits a 22.13 in depth, 24.88 in width, and 45.37 in height footprint. Plan for service clearances and access to the primary MCCB (JGE3160FAGC) and 280BPB wiring terminations while observing NEMA 2 enclosure requirements and UL listings.
RV48M28T4516CUPB provides a 480 V delta primary supply and a 208Y/120 V secondary, three-phase, 60 Hz. This arrangement supports control panels that need both high-voltage distribution and low-voltage control/logic power from a single transformer. Plan for appropriately rated breakers and bus connections, and ensure the 2.5% taps (two positive, four negative) are accommodated in the design.
Yes. The RV48M28T4516CUPB is DOE 2016 efficient, with 10 CFR Part 431 compliance and an electrostatic shield option. The 150 °C rise insulation and copper windings support reliable operation under DOE requirements, while UL Listing confirms safety and quality. Its ventilated design also helps minimize thermal losses in steady-state operation.
Expect UL Listed certification, DOE 2016 efficiency notes, and compliance with 10 CFR Part 431. The unit uses a NEMA 2 enclosure and a FR940SD frame with copper windings and 220 °C insulation, designed for floor- or wall-mount installation. Electrostatic shield is an available modification to reduce interference, and the product carries a standard one-year warranty.
Integrating this transformer typically reduces energy consumption through DOE 2016 efficiency and lowers cooling load thanks to its ventilated design. With a 45 kVA rating and full copper windings, it supports stable, reliable power for automation lines with minimal maintenance. The heavy-walled NEMA 2 enclosure and UL listing simplify regulatory compliance, while the integrated MCCB reduces parts count and maintenance overhead.
