Totally enclosed non-ventilated DT-3 design with aluminum windings reduces cooling requirements and protects windings from dust and moisture, lowering maintenance frequency. This configuration also minimizes fire risk and eliminates oil-related maintenance, which simplifies installation in confined spaces. Feature: 30 kVA rating with three-phase 480 V primary and 208Y/120 V secondary at 60 Hz. Business impact: Delivers reliable power to motor loads and control circuits, with capacity to accommodate peak demand and future expansion. Application: Plant-wide automation panels, motor control centers, and utility feeders in manufacturing facilities. Feature: Voltage taps of 2 at +2.5% FCAN and 4 at -2.5% FCBN allow precise voltage adjustment. Business impact: Maintains equipment within tolerances, reduces voltage-related outages, and extends life of sensitive components. Application: Facilities with long runs or fluctuating supply where voltage regulation matters. Feature: Compact enclosure with 22 in depth, 29 in width, 32.02 in height, and a 552 lb weight in a 914DN frame. Business impact: Facilitates site planning, forklift handling, and mounting in tight spaces without compromising service access. Application: Equipment rooms and crowded electrical closets in manufacturing lines. Feature: UL Listed certification and Eaton warranty (one year from installation or 18 months from shipment). Business impact: Strengthens regulatory compliance, reduces risk, and supports predictable maintenance budgeting. Application: Compliance-driven projects and procurement cycles in industrial facilities.

FAQs
Install the V48M28T30NV on a flat, level surface with adequate access for wiring and service. Dimensions are 22 in depth, 29 in width, and 32.02 in height, and it weighs about 552 lb, so plan for appropriate lifting and anchoring. Although the enclosure is totally enclosed and non-ventilated, leave sufficient space per local code to allow inspections and taps access.
Rated at 30 kVA with three-phase 480 V primary and 208Y/120 V secondary at 60 Hz. The transformer provides voltage regulation via taps: two at +2.5% FCAN and four at -2.5% FCBN, enabling minor voltage adjustments to compensate for load and supply variations.
Yes. The totally enclosed non-ventilated DT-3 dry-type transformer is designed for indoor electrical rooms, control panels, and switchgear rooms where safety, low fire risk, and minimal maintenance are priorities. Aluminum windings and a 150°C rise rating support reliable performance under high-load conditions common in manufacturing environments, with a compact 914DN frame for easy integration.
UL Listed certification confirms compliance with recognized safety standards for enclosed power transformers. The product carries Eaton's warranty policy: one year from installation or 18 months from shipment, whichever comes first. This combination supports risk mitigation, predictable maintenance budgeting, and documented support during critical plant outages.
As a dry-type transformer with aluminum windings, maintenance needs are minimized compared to oil-filled units. Plan for periodic visual inspections and connection verification, but expect low ongoing servicing. The 30 kVA rating, 60 Hz operation, and voltage taps support stable performance across varying loads, while the 552 lb weight requires appropriate handling equipment during installation.
