FAQs
To install the V48M64T12CUNV, mount the unit in a suitable indoor panel or equipment room with adequate clearance for access and cooling. Connect the 480 V primary to the supply bus and route the 240Y/139 V secondary to load feeders, ensuring proper wiring discipline, torque specs for copper windings, and alignment with the DT-3 enclosure for optimal heat dissipation and service access. Use the taps as needed for voltage regulation within the specified ±2.5% ranges to maintain stable loads.
Key specs include a 112.5 kVA rating, three-phase configuration, 480 V primary, 240Y/139 V secondary, 60 Hz operation, copper windings, and a 150°C rise. It features taps: 2 at +2.5% FCAN and 4 at -2.5% FCBN for voltage adjustment, and the DT-3 design with a frame 917N for robust installation and reliable long-term performance.
Yes. The transformer is a totally enclosed non-ventilated dry-type unit, designed to minimize dust and moisture ingress. UL Listed certification further supports compliance with safety standards, making it a good fit for challenging factory floors and environments where protection from contaminants improves reliability and reduces maintenance needs.
DT-3 indicates a dry-type distribution transformer with a robust, non-ventilated enclosure that simplifies cooling and reduces the risk of moisture ingress. This enhances reliability in indoor panels and compact electrical rooms, supports straightforward mounting with a sturdy 917N frame, and helps fit standard industrial layouts without complex ventilation requirements.
The V48M64T12CUNV carries Eaton’s standard warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. UL Listing provides additional confidence in safety and compliance. For ongoing maintenance, copper windings and dry-type insulation support longer service life with reduced lubrication and routine inspection needs.
