The 75 kVA three-phase transformer delivers compact, integrated protection with a built-in MCCB, enabling a smaller footprint and streamlined installation for Eaton-based control systems. This translates to reduced panel space, faster commissioning, and lower wiring complexity on projects requiring reliable 480 V to 208Y/120 V conversion. Copper windings provide high conductivity and thermal stability, improving efficiency and reducing heat losses in continuous operation, which supports energy savings and longer component life. The NEMA 2 enclosure and WS67 weathershield offer dependable dust and moisture protection in industrial spaces, minimizing downtime associated with harsh environments. Tap size options—2 at +2.5% and 4 at -2.5%—allow precise voltage adjustments to match varying loads, while the 80 °C rise specification ensures stability under peak demand. Compatibility with primary MCCB JGE3250FAGC, wiring connection 280BPBSB, and a floor-mount footprint enables straightforward integration into existing installations. Industry professionals appreciate the integrated features that reduce maintenance cycles, support compliance, and lower total cost of ownership in automation and power distribution applications.

FAQs
This unit is a 75 kVA, 3‑phase transformer with a 480 V primary and 208Y/120 V secondary, designed for floor mounting in industrial control panels. It features copper windings, a NEMA 2 enclosure, WS67 weather shield, and a primary MCCB (JGE3250FAGC). Wiring connection is 280BPBSB with tap settings of 2 at +2.5% and 4 at -2.5%, making it compatible with Eaton protection schemes and typical industrial power distributions.
The RV48M28B7516CUPBSB carries UL Listed certification and is DOE 2016 Efficient per 10 CFR Part 431 requirements. Catalog notes reference 10 CFR Part 431 (2016) Efficient, aligning with energy efficiency standards while providing reliable protection and performance for commercial and industrial installations.
Key ratings include 75 kVA, 60 Hz, three-phase operation, primary 480 V, secondary 208Y/120 V, and voltage rating 480 Vac-208Y/120 Vac with an 80 °C rise. This makes the transformer suitable for converting standard 480 V industrial feeds to safer, ready-to-use 208Y/120 V panel supplies in automation and process control.
The built-in primary MCCB JGE3250FAGC simplifies protection, reducing field wiring and potential fault points. This integration supports faster installation, improved fault isolation, and easier troubleshooting, leading to lower maintenance costs and enhanced equipment protection in uptime‑critical manufacturing environments.
Plan for floor mounting in a clean, dry space compatible with a NEMA 2 enclosure. Ensure proper clearance for ventilation and cooling, compatible with WS67 weather shield for exposed applications. Verify tap settings (2 at +2.5%, 4 at -2.5%) align with your load profile, and confirm wiring connections (280BPBSB) and protection devices match the primary MCCB specification.
