FAQs
Yes. The RV48M28T1216CUPBSB is a floor‑mount, three‑phase transformer with a 480 V primary and 208Y/120 V secondary, designed to fit standard distribution panels. Its NEMA 2 enclosure and built‑in MCCBs simplify mounting, wiring, and interconnection to existing feeders, reducing installation time and field wiring errors. Plan for a compatible footprint (31.5 in depth, 59.52 in height, 34.5 in width) and ensure adequate clearance for service access and ventilation.
Key ratings include 112.5 kVA, three‑phase operation at 60 Hz, primary 480 V, and secondary 208Y/120 V. It features copper windings and a 150 °C rise insulation, with primary MCCB LGE3400FAGC and secondary MCCB FR943SD 280BPBSB for integrated protection. The unit is UL Listed and DOE 2016 Efficient, aligning with safety and energy regulations for industrial power distribution.
Absolutely. The RV48M28T1216CUPBSB is designed for control panels and machine feeders, combining transformer functionality with breaker protection in a single enclosure. Its 480 V to 208Y/120 V output supports logic, PLCs, and motor starters. The compact footprint, integrated protection, and robust enclosure streamline panel design, wiring schedules, and preventive maintenance planning in manufacturing environments.
The unit is UL Listed and DOE 2016 Efficient compliant, meeting critical safety and energy standards for many North American projects. Compliance with these certifications reduces supplier risk, simplifies audits, and supports strategic sourcing for regulated facilities, data centers, and industrial plants that demand verified efficiency and protection performance.
Maintenance benefits stem from the integrated design: fewer external components, reduced wiring harnesses, and a consolidated protection scheme that simplifies diagnostics. The copper windings and high‑temp insulation support long life in hot environments, lowering replacement costs. ROI is driven by faster installation, lower field labor, improved energy efficiency under DOE 2016, and predictable lifecycle costs from UL‑listed, standards‑compliant equipment.
