Eaton Specification Sheet - N48M28T75AFEELS47
Feature: K-Factor nonlinear ventilated design provides improved harmonic management and cooler operation. Business impact: reduces overheating risk and maintains output stability under nonlinear loads, extending equipment life and lowering maintenance costs. Application: ideal for data centers, machine shops, and process lines where harmonics and switching devices are common. Feature: Voltage taps: 2 at +2.5%, 4 at -2.5% for on-site regulation. Business impact: enables fast, accurate voltage matching, minimizing nuisance trips and inventory needs. Application: feeders delivering 480 V to 208Y/120 V end equipment in variable grid conditions. Feature: NEMA 2 enclosure and low sound design (~47 dB). Business impact: enables installation in damp, occupied, or noise-sensitive spaces without compromising reliability. Application: control rooms, panel houses, and production floors near personnel. Feature: 75 kVA rating with 150 °C rise and 200 °C insulation system, aluminum coil, frame 916A, wiring 283B. Business impact: robust thermal margin supports continuous operation under high loads, reducing insulation breakdown risk and downtime. Application: medium-size plant feeders and distribution banks in harsh environments. Feature: Fungus-proof construction and WS19 weather shield. Business impact: extended service life in humid or outdoor installations; regulatory compliance and reduced maintenance. Application: outdoor or semi-outdoor plant areas and damp facilities. Feature: Documentation and compatibility with Eaton’s Transformer Flex Center and catalog notes. Business impact: accelerates installation planning, simplifies lifecycle management, and improves post‑install support. Application: new builds and modernization projects across manufacturing and process industries.

FAQs
This unit is a three‑phase transformer with a 480 V primary and a 208Y/120 V secondary, rated for 75 kVA and designed for 60 Hz operation. The configuration supports standard industrial power distribution with balanced phase loading and stable voltage under varying load. It also provides voltage stability under harmonic and switching conditions to protect sensitive equipment.
The transformer offers two taps at +2.5% and four taps at -2.5% for on-site regulation. Operators can select taps to compensate for voltage drop along feeders or input fluctuations, reducing voltage mismatch and avoiding nuisance trips in motor drives and control circuits. Proper tap selection supports consistent performance across load swings.
Yes. The transformer is UL Listed and housed in a NEMA 2 enclosure with fungus-proof design for damp locations. For outdoor or highly humid installations, WS19 weather shield provides additional protection, ensuring reliable operation and regulatory compliance in plant floors and switchgear areas.
The catalog notes indicate a low sound design of approximately 47 dB, which minimizes acoustic impact in occupied spaces and near control rooms. This helps meet site noise limits without extra attenuation, simplifying installation and reducing enclosure footprint in compact facilities.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first (policy 25-000). Field support includes access to Eaton specification sheets and catalogs, plus guidance for compatibility with Eaton Transformer Flex Center for lifecycle and preventive maintenance planning.
