FAQs
Plan for a dedicated, ventilated or climate-controlled enclosure, ensure floor mounting or rack-ready placement for the 36.23 in length and 75 in height, and provide required clearance for cooling and maintenance. Use the 480 V primary and 230Y/133 V secondary wiring scheme with properly rated lugs and shielded connections. Verify the field taps (+2.5% and -2.5%) are set per site voltage conditions and perform a full insulation test prior to energizing the system.
Confirm 300 kVA kVA rating, three-phase operation at 60 Hz, 480 V primary, 230Y/133 V secondary, copper windings, and DT-3 design. Check tap positions: 2 taps at +2.5% FCAN and 4 taps at -2.5% FCBN. Ensure the frame is 919NE and that the installation accommodates a 150°C rise rating to support expected thermal conditions.
Yes, the V48M63T33TCUNV is designed for reliable three-phase power distribution in industrial environments. Its totally enclosed non-ventilated construction minimizes dust ingress, UL Listed safety certification facilitates compliance, and the 300 kVA rating supports critical loads common in data centers and manufacturing lines while enabling scalable downstream distribution.
The transformer carries UL Listed certification, signaling safety compliance for industrial use. Maintenance benefits come from the dry-type, sealed design that reduces cooling system dependencies. Expect a standard one-year warranty from installation or 18 months from shipment, whichever occurs first, providing a clear baseline for support and service planning.
The unit’s low maintenance, rugged copper-wound construction, and compact DT-3 design translate to reduced downtime and longer service intervals. Its solid protection against dust ingress and robust third-phase performance support steady operation of downstream loads, improving overall equipment effectiveness (OEE) and lowering total cost of ownership over the transformer’s lifespan.
