FAQs
Yes. The V29D47B30CUNV uses a totally enclosed non-ventilated design and a compact 915DN frame, making it well suited for control panels and restricted spaces. Its 22x39.18x29 inch footprint and copper windings provide reliable operation with straightforward mounting and maintenance.
The unit is a 30 kVA, three-phase transformer with a 208 V primary and 480Y/277 V secondary. It includes copper windings, 60 Hz operation, and voltage taps at +2.5% and -2.5% to accommodate supply variations, supporting flexible site integration and reduced voltage drop.
Voltage taps provide a practical way to compensate for line drop and minor supply fluctuations. With two taps at +2.5% and two at -2.5%, you can tune the output to match downstream equipment, minimizing nuisance tripping and improving control panel reliability.
The transformer carries UL Listed certification, indicating compliance with recognized safety standards for electrical equipment. This is important for procurement approvals, installation safety, and ongoing regulatory compliance across industrial facilities.
As a dry-type, copper-wound transformer with a totally enclosed non-ventilated design, it requires minimal routine cooling maintenance and no oil handling. The unit ships with Eaton’s 1-year warranty (18 months from shipment), offering protection during early operation and a clear support path for lifecycle planning.
