Eaton RV48M28F1216CUPB Breaker-Integrated Transformer - UL Listed
Part Number: RV48M28F1216CUPB
Quick Summary
RV48M28F1216CUPB is an integrated transformer and MCCB assembly for 3-phase industrial power protection. It combines a ventilated transformer with a primary MCCB, delivering reliable protection in a compact floor-mount package. Facility teams often struggle with space constraints and wiring complexity when protecting transformers and feeders separately, which can lead to longer installation times and higher risk of misconfigurations. This Eaton solution carries UL Listed safety certification and a DOE 2016 Efficient rating, with a rugged NEMA 2 enclosure for indoor environments. The design also supports voltage regulation through tap settings and a copper-winding build for durability. By consolidating protection and transformation, it reduces footprint, simplifies maintenance, and supports efficient energy management in electrical distribution for automation and manufacturing applications.

FAQs
Yes. The unit is designed for floor mounting with dimensions of 31.5 in long, 34.5 in wide, and 59.52 in high. Plan for adequate clearance at the top and sides for ventilation, wiring access, and service, and ensure a level surface that supports the enclosure weight and vibration tolerance of a 112.50 kVA, three-phase system.
The RV48M28F1216CUPB provides a 112.50 kVA, three-phase transformer with 480 V primary and 208Y/120 V secondary at 60 Hz, plus a 115 Ā°C rise rating. This enables robust energy transfer with favorable voltage regulation, supports standard industrial motors and controls, and helps maintain consistent performance under load fluctuations common in manufacturing environments.
The assembly is UL Listed for safety and complies with DOE 2016 Efficient standards, supporting energy-conscious operation. These certifications help ensure regulatory compliance, safety for personnel, and reduced energy losses in large-scale installations, which is critical for industrial facilities pursuing efficiency targets and audit readiness.
Best suited for machine automation panels, control rooms, and industrial power distribution where space is at a premium. Its integrated primary MCCB (JGE3200FAGC) simplifies protection coordination, while the 208Y/120 V secondary suits control circuits and low-voltage auxiliaries on the line, making it ideal for panelboard retrofits and new equipment layouts in manufacturing and data centers.
The integrated transformer-breaker reduces cabinet footprint, minimizes interconnection labor, and lowers servicing complexity by containing protection and transformation in one enclosure. This translates to faster commissioning, lower installation costs, easier spare-part management (280BPB connections), and improved uptime, delivering tangible ROI in capital projects and ongoing maintenance budgets.
