Electrostatically Shielded
Totally enclosed non-ventilated enclosure reduces dust and moisture ingress, protecting insulation and extending service intervals. This directly lowers maintenance costs and minimizes unexpected downtime in harsh plant environments. It is ideal for factory floors, outdoor equipment huts, and other locations where ventilation is impractical. K-13 design supports non-linear loading and a 150°C rise, allowing a compact, aluminum-windings transformer without sacrificing reliability. The business impact is improved thermal management, enabling shorter cooling cycles and reduced energy losses. Applications include high-load machinery, presses, and automated lines where peak demand spikes occur. Dual voltage capability with a 480 V primary and 208Y/120 V secondary, plus taps at +2.5% FCAN and -2.5% FCBN, delivers tight voltage regulation. This reduces control circuit stress and extends life of sensitive automation components. Applications include PLCs, drives, sensors, and control panels requiring stable voltage. Frame 914DN with dimensions 22 in L x 29 in W x 39.18 in H and a weight of 507 lb simplifies cabinet and room planning, enabling straightforward installation and service access. Electrostatic shield minimizes EMI coupling to control circuits, protecting signal integrity in noisy factory floors and supporting reliable operation of automation equipment. UL Listed safety certification confirms compliance; warranty is one year from installation or 18 months from shipment, reducing long-term risk and supporting predictable total cost of ownership.

FAQs
Install the N48M28T30NV on a compatible 914DN frame with adequate clearance for access, wiring, and cooling. The unit operates at 60 Hz three-phase with a 480 V primary and 208Y/120 V secondary, and includes taps at +2.5% and -2.5%. Use aluminum windings, proper grounding, and Electrostatic Shielding to minimize EMI in control panels.
Key specs include a 30 kVA rating, 480 V primary, 208Y/120 V secondary, 60 Hz, three-phase operation, and a K-13 non-linear design. It features aluminum windings, an electrostatic shield, a frame 914DN, and a 150°C rise rating. Taps provide voltage adjustments (+2.5% FCAN and -2.5% FCBN) for tighter regulation in variable loads.
Yes. Its totally enclosed non-ventilated enclosure minimizes dust and moisture ingress, supporting uptime in harsh environments. The K-13 design handles higher temperature rise, and the electrostatic shield protects control circuits from EMI. With a 30 kVA rating and dual voltage outputs, it reliably powers PLCs, drives, and sensors in automated facilities.
The N48M28T30NV carries UL Listed certification for safety compliance. The data sheet does not specify CE or IP ratings. When planning compliance, verify compatibility with local electrical standards and enclosure requirements, and consult Eaton documentation for the latest certification status and suggested installation practices.
Warranty terms state one year from installation or eighteen months from shipment, whichever occurs first. Eaton provides standard product support and replacement options under policy 25-000. For maintenance planning, schedule periodic inspections, verify insulation integrity, and ensure connections remain secure to maximize uptime and total cost of ownership.
