Eaton Specification Sheet - N48M28T12AFEELS47
Feature to Business Impact to Application: The N48M28T12AFEELS47 offers three-phase operation at 60 Hz with a 112.5 kVA rating, enabling large-load support and reliable distribution for manufacturing lines and machine controls, reducing voltage dips and improving equipment lifespan in demanding facilities. The voltage taps—two at +2.5% and four at -2.5%—enable on-site voltage regulation to maintain motor performance and protection in variable load scenarios across control rooms and production zones. Aluminum windings paired with a 150 °C rise rating enhance thermal resilience, allowing longer duty cycles in hot environments such as welding stations and concentrated load racks. The NEMA 2 enclosure and WS19 weather shield deliver rugged, easy integration into indoor plant rooms or semi-exposed electrical spaces with minimal additional protection. Electrostatically shielded construction reduces EMI, supporting sensitive drives and PLCs in automation architectures. Fungus-proof construction ensures reliability in humid or damp facilities, minimizing maintenance and replacement costs over time.

FAQs
For proper installation, ensure a three-phase 480 V supply feeding the 480 V primary, with the secondary delivering 208Y/120 V to downstream equipment. The unit weighs 1000 lb, requires suitable mounting and clearances per manufacturer guidelines, and uses a NEMA 2 enclosure with 283B wiring; plan for on-site voltage tapping access (+/-2.5% taps) and appropriate cooling clearance in hot environments.
Core specs include 112.5 kVA VA rating, 60 Hz frequency, primary voltage 480 V, secondary voltage 208 Y/120 V, three-phase configuration, and voltage taps of 2 at +2.5% and 4 at -2.5%. It features aluminum windings and supports a 150 °C rise, with UL Listed certification and NEMA TP-1 efficiency for reliable industrial performance.
Yes. The 112.5 kVA, 480 V to 208Y/120 V three-phase design supports critical loads in data centers and automation lines. Its low-noise 47 dB profile, electrostatic shielding, and fungus-proof construction improve reliability in sensitive environments, while voltage taps aid precise regulation for varied IT and control equipment demands.
The unit is UL Listed and designed for NEMA TP-1 efficiency. It also features fungus-proof construction, and a 150 °C rise rating which supports safe operation in demanding installations. Additional attributes include electrostatic shielding for EMI control and WS19 weather shielding for suitable siting in semi-exposed spaces.
Expect lower maintenance due to robust construction (fungus-proof, electrostatic shielding) and a long expected service life in harsh environments. The UL listing and NEMA TP-1 efficiency support compliant operation, reducing risk of downtime. The voltage taps enable on-site regulation, helping minimize energy waste and improve overall system reliability and ROI.
