Eaton N48M28T50EE Transformer - UL Listed, 50 kVA
Part Number: N48M28T50EE
Quick Summary
Eaton N48M28T50EE transformer provides reliable three-phase voltage conversion for plant power distribution. Engineers often wrestle with overheating and efficiency losses when supplying nonlinear loads, but this unit uses a K-Factor nonlinear design and forced ventilation to keep temperatures in check. It carries UL Listed certification and is NEMA TP-1 compliant, with catalog notes confirming NEMA TP-1 efficient performance. This combination supports safer operation and longer equipment life in harsh industrial environments. For system integrators, the model’s 50 kVA rating and 480 V primary to 208Y/120 V secondary configuration offer scalable, compliant power delivery while reducing energy waste and maintenance costs over the life of the installation.

Eaton Specification Sheet - N48M28T50EE
Feature: K-Factor nonlinear ventilation minimizes heat buildup under nonlinear loading. Business impact: improves reliability and extends transformer life by maintaining safe temperatures even during peak harmonic demand. Application: ideal for motor drives, presses, and other equipment with distorted loads in manufacturing floors and distribution rooms. Feature: 50 kVA three-phase transformer with 480 V primary and 208Y/120 V secondary. Business impact: supports critical downstream loads with stable voltages and minimal voltage drop, reducing equipment misoperation and downtime. Application: panel boards, MCCs, and control centers in factories and processing plants. Feature: Tap changes 2 at +2.5% and 4 at -2.5%. Business impact: maintains output voltage within tolerance despite source variation or load changes, reducing equipment stress. Application: critical power rails, instrument panels, and harmonics-sensitive circuits. Feature: Electrostatic shielding with WS39 weather shield and aluminum windings. Business impact: reduces EMI coupling and enables outdoor or harsh-environment installation, lowering enclosure cooling costs. Application: outdoor cabinets, data centers near heavy equipment, and outdoor substations. Feature: Compliance and efficiency indicators — NEMA TP-1 compliant, UL Listed, and catalog notes noting NEMA TP-1 efficiency. Business impact: procurement-ready, regulatory-aligned performance with lower life-cycle cost. Application: new builds and upgrades across industrial plants requiring reliable standards compliance.

FAQs
Plan for a three-phase installation with a 50 kVA rating, 480 V primary, and 208Y/120 V secondary. Ensure adequate ventilation for the K-Factor nonlinear design, confirm WS39 weather-shield suitability, and allow space for the 22x39x29 in footprint. Verify alignment with UL Listed and NEMA TP-1 compliance during panel assembly.
The K-Factor nonlinear design anticipates harmonic conditions and reduces heat buildup, keeping winding temperatures within safe limits. This improves reliability, extends service life, and lowers maintenance frequency, particularly in facilities with motor drives and high-harmonic equipment.
Yes. With 50 kVA capacity, 480 V to 208Y/120 V support, and robust ventilation, it is suited for data centers, MCCs, and motor-control panels that require stable voltages and adherence to NEMA TP-1 efficiency and UL safety standards.
The unit is UL Listed and NEMA TP-1 compliant, with catalog notes confirming NEMA TP-1 efficiency. These certifications ensure regulatory compliance, safer operation, and predictable performance in industrial environments, which is critical for audits and procurement approvals.
Warranty follows Eaton policy 25-000: one year from installation or 18 months from shipment, whichever comes first. The ventilated, shielded design reduces overheating risk and routine maintenance, contributing to lower total cost of ownership over the life of the installation.
