FAQs
The RV48M28T2216CUPBSB is a three-phase transformer rated at 225 kVA with a 480 V primary and 208Y/120 V secondary, designed for 60 Hz operation. It mounts floorward in indoor spaces (NEMA 2) and includes copper windings and an integrated primary MCCB for simplified wiring and faster commissioning in control panels and machine rooms.
This unit combines a 225 kVA transformer with an integrated primary MCCB (NGS308033EC) and a compatible secondary protection scheme, reducing the number of separate components and connections. The result is easier panel assembly, improved fault isolation, and quicker maintenance in motor control centers and control cages.
It is UL Listed for safety, complies with DOE 2016 Efficient requirements, and adheres to 10 CFR Part 431 efficiency standards, supporting regulatory compliance and energy performance. The NEMA 2 enclosure further specifies indoor protection, contributing to overall reliability in industrial environments.
The transformer provides two taps at +2.5% and four taps at -2.5%, allowing voltage adjustment to compensate supply variances. This helps maintain downstream voltage within tolerance for sensitive equipment, reduces nuisance tripping, and supports stable operation in fluctuating facilities and production lines.
By integrating protection and transformer functions, reducing wiring complexity, and meeting efficiency standards, this unit minimizes installation time and energy losses. The robust NEMA 2 enclosure, copper windings, and inline MCCB contribute to lower maintenance costs and higher uptime in manufacturing or process environments.
