FAQs
Plan for a fixed, level mounting surface in a climate-controlled indoor space to maintain the 32.65 in length, 36.6 in width, and 57.5 in height. Allow adequate clearance for the enclosure and service access, and ensure the unit is connected to a suitable 480 V mains with proper 3-phase wiring. The DT-3 frame and UL Listed status simplify site acceptance and regulatory review.
The transformer delivers 112.5 kVA with a 480 V primary and 208Y/120 V secondary, operating at 60 Hz. Aluminum windings and an 80°C rise support reliable operation under load. Voltage taps include 2 at +2.5% FCAN and 4 at -2.5% FCBN for field voltage adjustment, enabling stable downstream equipment performance.
Yes. With a three-phase configuration, 112.5 kVA rating, and 480 V to 208Y/120 V outputs, it matches standard control panels and process equipment. The totally enclosed non-ventilated design reduces dust and moisture ingress, while aluminum windings improve efficiency. The UL Listed certification adds procurement confidence and regulatory alignment.
The V48M28B12NV carries UL Listed certification, indicating compliance with recognized electrical safety standards. This supports safer installation in industrial facilities and streamlines supplier qualification, maintenance planning, and regulatory audits. Always follow Eaton installation guidelines and local electrical codes when applying voltage taps and enclosure specs.
Maintenance needs are minimized by the dry-type design and enclosure protection, reducing cooling requirements and dust ingress. Expect long service life with aluminum windings and a robust frame, backed by a one-year warranty (or eighteen months from shipment per Eaton policy). A reliable 112.5 kVA supply can lower downtime, improve productivity, and reduce total cost of ownership in high-demand environments.
