Feature → Business Impact → Application: The RV48M28F2216CUPB uses 225 kVA three-phase transformation with a 480 V primary and 208Y/120 V secondary, enabling robust power distribution to medium-sized motor control centers with reduced wiring complexity and a smaller footprint. This compact, integrated solution improves reliability and lowers installation costs by consolidating transformer and protection functions in a single cabinet, ideal for space-constrained plant rooms and switchgear enclosures. Feature → Business Impact → Application: Copper windings and a 263 °C insulation class enhance thermal performance and durability under continuous duty, improving long-term efficiency and reducing maintenance cycles for critical loads in manufacturing lines and process controls. Feature → Business Impact → Application: Tap changer options (2 at +2.5%, 4 at -2.5%) provide flexibility to accommodate voltage fluctuations on sensitive equipment, improving protection for programmable logic controllers and servo systems. Feature → Business Impact → Application: A NEMA 2 enclosure with WS68 weather shield supports indoor and semi-exposed installations, enabling outdoor-rated or semi-enclosed applications in harsh industrial environments without additional housings. Feature → Business Impact → Application: Primary MCCB integration (LGE3400FAGC) simplifies compliance with safety standards and aids fast fault isolation, reducing downtime during maintenance and startup in new distribution boards and retrofits. Feature → Business Impact → Application: DOE 2016 efficiency and UL listing demonstrate regulatory compliance and energy savings, lowering lifecycle energy costs and facilitating purchaser audits for facilities governed by energy standards and procurement policies.

FAQs
Plan for a floor-mounted footprint of approximately 33.7 in deep, 38 in wide, and 68.54 in tall. Ensure adequate clearance for cooling and access to the primary MCCB LGE3400FAGC, and place the unit on a level, vibration-free surface. The NEMA 2 enclosure and WS68 weather shield support indoor and semi-outdoor locations, reducing the need for extra housings.
This transformer delivers 225 kVA at 60 Hz, with a 480 V primary and 208Y/120 V secondary. Copper windings and a 263 °C insulation class support high thermal tolerance. Tap settings are 2 at +2.5% and 4 at -2.5%, enabling voltage adjustment to protect connected equipment and improve regulatory compliance in fluctuating supply environments.
Yes. The RV48M28F2216CUPB features a primary MCCB integration with LGE3400FAGC, simplifying cabinet design, enhancing fault isolation, and reducing wiring complexity. This tight integration lowers installation time, improves startup reliability, and streamlines maintenance in control panels and motor control centers.
The unit is UL Listed and DOE 2016 Efficient under 10 CFR Part 431, ensuring compliance with safety and energy efficiency regulations. It also carries a NEMA 2 enclosure and WS68 weather shield for rugged environments, making it suitable for industrial facilities seeking regulatory alignment and reliability in demanding conditions.
The combination of DOE efficiency, copper windings, and a compact, integrated package reduces energy losses, installation labor, and spare parts. The rugged enclosure and built-in protection minimize downtime, while the selectable taps and strong warranty support predictable performance, supporting a favorable total cost of ownership in facilities with frequent power disturbances and stringent compliance requirements.
