Feature → Business Impact → Application: The K-Factor nonlinear ventilated design reduces core and copper losses, delivering lower operating temperatures and improved efficiency under variable loads. This translates to measurable energy savings on a 30 kVA, 480 V input with a 400Y/231 V output and minimizes heat rejection, easing cooling requirements in hot plants. Aluminum windings improve heat dissipation while reducing weight, supporting easier handling and site installation for 3-phase power distribution. The FR940 frame provides rugged support for field service in demanding environments, helping maintenance teams schedule timely interventions without disrupting production. With a 60 Hz frequency rating and a 150 °C rise, the transformer maintains stable performance in high-temperature facilities, supporting regulatory compliance and long-term reliability. The 283B wiring connection and blank tap provisions offer flexible site wiring and voltage regulation to match local supply conditions. In practice, this translates to fewer field reworks, improved voltage stability, and lower lifecycle costs for motor loads and distribution circuits. Warranty coverage under Eaton policy 25-000 adds another layer of financial protection for engineering teams managing long-term capital projects.

FAQs
N48M34T3016 is designed for a 480 V primary three-phase supply and delivers a 400Y/231 V secondary. It features a 283B wiring connection and 2 at +2.5% and 4 at -2.5% tap settings to fine-tune voltage, enabling stable operation across common industrial distribution schemes and reducing off-load voltage instability.
The unit comes in a NEMA 2 enclosure and supports floor or wall mounting. It weighs approximately 407 lb with dimensions around 21.13 in L, 36.77 in H, and 24.86 in W. The 283B wiring connection simplifies field wiring, and the WS58 weather shield option helps protect it in exposed locations.
It complies with DOE 2016 Efficient standards and 10 CFR Part 431 guidance, with UL Listed certification. This reduces regulatory risk, supports energy-cost savings, and simplifies procurement where DOE compliance is a project prerequisite for funding or audit requirements.
Eaton provides a warranty under policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This protects against manufacturing defects and supports maintenance planning for capital equipment in production facilities.
Ideal for manufacturing lines, process plants, and distribution rooms requiring reliable 30 kVA three-phase power. The transformer’s rugged NEMA 2 enclosure, aluminum windings, and DOE 2016 efficiency make it suitable for hot, dusty factory floors and spaces with space constraints, delivering cost-per-kW improvements and predictable performance.
