FAQs
The V48M22T12CUNV is a three-phase dry-type transformer with a compact footprint that fits typical industrial control panel layouts. Its 24.67 in L x 31.44 in W x 56.18 in H enclosure accommodates standard mounting provisions, while the DT-3 design minimizes enclosure heat buildup. This makes installation straightforward for panel builders and facility engineers, helping to reduce integration time and wiring complexity.
Key specs include a 112.5 kVA rating, 480 V primary, and 240/120 V secondary in a three-phase configuration at 60 Hz. Copper windings and a 150°C rise support robust performance under demanding loads. Dual taps (+2.5% FCAN, -2.5% FCBN) provide voltage adjustment to maintain stable outputs for critical equipment.
Yes. It uses a totally enclosed non-ventilated enclosure and copper windings designed to resist dust and contaminants common in factories. UL Listed certification adds safety and reliability, while the DT-3 dry-type construction helps sustain performance in environments with variable temperatures and limited maintenance windows.
The product is covered by Eaton’s standard warranty policy, offering one year from installation or eighteen months from shipment, whichever occurs first. Maintenance needs are typical for dry-type transformers: periodic inspection, tap setting verification, and enclosure integrity checks help ensure consistent performance and longevity.
Plan for a dedicated pad or cabinet space with dimensions 24.67 in by 31.44 in by 56.18 in and an estimated weight of 1685 lb. Ensure proper mounting to frame 917N, account for 480 V to 240/120 V distribution, and include space for taps and wiring access. Consider heat dissipation, wiring clearance, and compliance with UL-listed installation practices.
