Eaton N48M31F75CU Nonlinear Ventilated Transformer - UL Listed
Part Number: N48M31F75CU
Quick Summary
Eaton N48M31F75CU nonlinear ventilated transformer reliably steps down 480 V three-phase power for critical power systems. Operators struggle with voltage variability, downtime, and cooling costs when transformer performance is marginal. UL Listed safety certification and a rugged NEMA 2 enclosure provide regulatory compliance and protection in harsh environments, while the copper windings and electrostatic shielding enhance isolation and longevity. This model supports tight voltage regulation and high thermal performance, reducing energy waste and maintenance. In industrial power management, predictable voltage, fast tap adjustments, and durable construction translate to improved uptime and lower total cost of ownership, especially in data centers and continuous-process facilities.

FAQs
Plan for a three-phase, 480 V input with a 220Y/127 V secondary distribution to downstream equipment. Ensure adequate space for a heavy unit (951 lb) and provide proper ventilation for the NEMA 2 enclosure. Verify wiring uses 283B connections and align with the +2.5% and -2.5% tap settings to maintain voltage stability under load.
KT-13 nonlinear design optimizes flux distribution to reduce core losses and hot spots, improving voltage regulation under transient loads. Coupled with copper windings and ventilation, this yields better thermal margins, enabling higher reliability and longer service life in continuous industrial operation.
Yes. With 75 kVA three-phase capacity, 480 V primary, 220Y/127 V secondary, and robust protection (UL Listed, NEMA 2 enclosure, electrostatic shielding), it supports critical loads in data centers and manufacturing lines. Its taps and 60 Hz compatibility help maintain stable voltages for sensitive equipment and motors alike.
The transformer is UL Listed for safety compliance and comes in a NEMA 2 enclosure, offering indoor protection against dust and moisture. Electrostatic shielding enhances safety and isolation, while WS19 weather shielding provides added protection in suitable indoor environments.
Eaton provides a warranty per policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. Regular visual checks, periodic insulation tests, and temperature monitoring of the enclosure improve reliability and prevent unexpected downtime, supporting a favorable TCO for long-term industrial usage.
