Eaton Specification Sheet - N48M28F30CUNVLS45
K-Factor nonlinear design (K-13) delivers reduced harmonic distortion and cleaner voltage in nonlinear loads, which lowers equipment stress and extends motor life. This translates to fewer nuisance trips and improved uptime in drives and automation panels. The 30 kVA rating coupled with a 480 V to 208Y/120 V output supports substantial loads with room to scale in switchgear and distribution panels. The voltage taps—2 at +2.5% and 4 at -2.5%—provide practical flexibility to compensate for supply fluctuations, reducing voltage drift and optimizing performance at remote sites or with fluctuating inputs. Copper windings and a 115 °C rise design enhance insulation reliability and thermal endurance, while an electrostatic shield adds EMI protection for sensitive electronics in harsh environments. The enclosure is totally enclosed non-ventilated with a low 45 dB sound footprint, enabling quiet operation in customer-facing or confined spaces. UL Listed certification supports procurement and compliance, while the robust 916AN frame and a weight of 968 lb ensure durable service in demanding industrial settings. Finally, the compact footprint and panel-friendly dimensions simplify integration and mounting within existing electrical rooms.

FAQs
This transformer uses a 916AN frame and weighs about 968 lb, with overall dimensions of 23.42 in (depth) by 28.22 in (width) by 46.58 in (height). It is designed as a totally enclosed non-ventilated unit with a low 45 dB sound level, making it suitable for cabinet or wall mounting in service corridors or electrical rooms where space and noise limits matter. Ensure adequate clearance for service access and connection wiring per Eaton installation guidelines.
The N48M28F30CUNVLS45 is a three-phase, 60 Hz transformer rated at 30 kVA with a 480 V primary and 208Y/120 V secondary. It has copper windings, an electrostatic shield, and a temperature rise of 115 °C. Voltage taps include 2 at +2.5% and 4 at -2.5%, supporting site voltage variation. The enclosure is totally enclosed and non-ventilated, designed for reliability in industrial environments.
Yes, the N48M28F30CUNVLS45 is well-suited for data centers, manufacturing floors, and other heavy-industrial applications. Its K-Factor nonlinear design manages non-linear loads, while the electrostatic shield mitigates EMI risks to sensitive equipment. The 30 kVA capacity provides ample headroom for critical drives and protection schemes, and the UL Listed certification supports compliance and procurement in regulated facilities.
The transformer is UL Listed, confirming compliance with essential safety standards for electrical distribution equipment. This certification simplifies procurement for regulated environments and cachet for integrators handling electrical installations. The unit’s totally enclosed non-ventilated construction and low-noise profile also align with facility requirements for noise-sensitive areas, while copper windings and shielding contribute to durability and performance.
ROI benefits arise from improved power quality, reduced downtime, and lower maintenance costs. The copper windings and robust insulation with 115 °C rise support long service life in demanding environments. Voltage taps reduce voltage drift, while EMI shielding minimizes failures due to electrical noise. A one-year warranty (or eighteen months from shipment per Eaton policy) provides initial risk protection for procurement.
