Eaton N48M28T75AFEE Nonlinear Ventilated Transformer - UL
Part Number: N48M28T75AFEE
Quick Summary
The Eaton N48M28T75AFEE is a nonlinear ventilated transformer for three-phase power distribution in industrial facilities. This design helps engineers protect sensitive loads and keep critical systems within tolerance during brownouts. UL Listed certification and NEMA 2 enclosure provide safety and environmental protection, while NEMA TP-1 efficient design lowers energy loss across duty cycles. With selectable taps for +2.5% / -2.5%, 150°C rise insulation, and fungus-proof construction, it adapts to harsh plant conditions, delivering reliable, long-life operation. In practice, this reduces spare parts usage, shortens commissioning times, and improves ROI across industrial power distribution networks. Its rugged, fungus-proof enclosure and electrostatically shielded coil design help meet facility reliability targets.

Eaton Specification Sheet - N48M28T75AFEE
Feature: K-Factor nonlinear transformer design minimizes overheating and harmonic distortion under variable loads. Business Impact: Preserves voltage integrity for sensitive equipment, extends transformer life, and reduces maintenance costs in continuous operation environments. Application: ideal for manufacturing lines with variable loads and data-center power conditioning. The second key feature is a 75 kVA three-phase rating with a 480 V primary and 208Y/120 V secondary, enabling compact, centralized distribution and reducing panel complexity on the shop floor. Tap options include 2 at +2.5% and 4 at -2.5% to compensate for voltage drift, delivering tighter voltage control and preventing downstream equipment excursions. Application contexts include control panels, machine tooling, and distribution boards where precise regulation matters. A rugged build combines aluminum coils, an electrostatically shielded design, NEMA 2 enclosure, and WS19 weather shield for durable operation in challenging environments. These characteristics support reliability, lower lifecycle costs, and easier maintenance.Additional benefits include UL Listed safety certification and NEMA TP-1 efficiency guidance, contributing to energy savings and compliance in industrial settings. The product’s 150°C rise capability with a 200°C insulation system enables operation in hot factories, while fungus-proof construction reduces environmental risk. The overall installation is supported by a manageable footprint and robust mounting options, improving project timelines and reducing downtime during retrofits. With a weight of 717 lb and a footprint around 28.22 in by 23.42 in, it offers a stable, long-life solution for demanding industrial power management.

FAQs
Install with the 480V primary connected to the 283B wiring terminals, following MRP torque specifications and using appropriate gland seals. Mount the unit on a solid, level surface with adequate clearance for ventilation. Connect the secondary to 208Y/120V distribution panels, ensure proper grounding, and verify tap settings (+2.5% or -2.5%) to match site voltage. Verify 60 Hz supply and confirm UL Listed safety guidelines are followed during commissioning.
Key specs include a 75 kVA three-phase rating, 480 V primary, 208Y/120 V secondary, 60 Hz operation, and a temperature rise of 150°C with a 200°C insulation system. It uses aluminum coil construction, an electrostatically shielded design, and a NEMA 2 enclosure with WS19 weather shield. Tap options are 2 at +2.5% and 4 at -2.5% for voltage regulation in varying conditions.
Yes. The combination of robust voltage regulation, harmonic tolerance through K-Factor design, and rugged enclosure makes it well-suited for data centers and manufacturing floors. Its 75 kVA rating supports power conditioning for critical loads, while the UL Listed safety and NEMA TP-1 efficiency help meet industry standards and reduce energy waste in demanding environments.
This model is UL Listed, guaranteeing electrical safety compliance. It complies with NEMA 2 enclosure protection for indoor durability and WS19 weather shield as an environmental feature. Additionally, its design aligns with NEMA TP-1 efficiency expectations, aiding energy performance and regulatory alignment in industrial facilities.
Expect lower maintenance costs due to improved reliability from the fungus-proof enclosure, aluminum coils, and electrostatic shielding. The 75 kVA rating reduces spare-part diversity and installation complexity, while the unit’s efficiency and voltage regulation minimize energy losses. A typical ROI improvement comes from reduced downtime, easier commissioning, and longer service life, backed by a one-year warranty or eighteen months from shipment depending on policy.
