Eaton N48M28T45LS42 Nonlinear Transformer - UL Listed
Part Number: N48M28T45LS42
Quick Summary
Eaton N48M28T45LS42 nonlinear ventilated transformer is a reliable three-phase power solution for industrial automation and distribution. In demanding installations, harmonics, heat, and audible noise can erode uptime and complicate regulatory compliance. This model carries UL Listed safety certification; while CE and IP ratings are common benchmarks for similar products, they are not listed for this unit. The K‑Factor design, 150°C rise, and electrostatic shield optimize power quality and protection for sensitive loads. Aluminum windings in a ventilated frame support efficient cooling and reduced copper loss across load swings. WS39 weather shield and a low 42 dB sound profile enable straightforward deployment in industrial floors, switchgear, and outdoor enclosures, delivering predictable business value.

Eaton Specification Sheet - N48M28T45LS42
K-Factor nonlinear design reduces harmonic stress on transformers and downstream equipment, improving power quality and extending the life of drives, motors, and control electronics. The N48M28T45LS42 achieves better current waveform management at typical 60 Hz operation, reducing stray voltages and overheating in harmonics-rich environments. For engineers, this translates into longer maintenance intervals and fewer nuisance trips in production lines that rely on PWM drives and variable-frequency drives. Ventilated frame design (914D) combined with aluminum windings delivers superior cooling compared with solid-core variants. This arrangement minimizes copper loss under varying load, supports higher heat rise tolerance (150 °C), and maintains stable output during peak demand. In compact switchgear or panel enclosures, the improved heat dissipation reduces derating and simplifies airflow planning. Taps: 2 at +2.5% FCAN and 4 at -2.5% FCBN provide practical voltage regulation to counter feeder drop or surge without external tap-changing gear. This capability eases commissioning, supports tighter voltage bands for sensitive equipment, and helps meet tolerance specs for downstream controls. The 480 V to 208Y/120 V secondary configuration also aligns with common plant architectures. WS39 weathershield adds weather resistance for outdoor or harsh industrial environments, while the low sound level of 42 dB makes siting in noise-sensitive areas feasible. The electrostatic shield protects against EMI, improving reliability for nearby communications and control networks. The frame 914D and UL Listed status further simplify procurement, installation, and regulatory compliance. Warranty and support: Eaton’s policy 25-000 offers one year from installation or 18 months from shipment, whichever occurs first, reducing risk during initial operation. The product carries UL Listed certification, a solid safety indicator for procurement teams, and access to Eaton technical data sheets and transformer catalogs for integration and spares. Together these factors deliver a clear ROI by minimizing downtime and maintenance costs.

FAQs
Ensure adequate clearance for the 22 in depth, 29 in width, and 39 in height footprint. Plan ventilation to support the 150°C rise specification, mount on suitable rails or base, and verify 60 Hz input with the 480 V primary and 208Y/120 V secondary. Consider the WS39 weather shield if installed outdoors and confirm EMI shielding requirements with nearby equipment.
The transformer uses a K-Factor nonlinear design that mitigates harmonic stress on both the transformer and downstream drives. Combined with aluminum windings and an electrostatic shield, it preserves waveform integrity, reduces overheating risk, and supports stable voltage delivery in PWM-driven equipment common to motor drives and process automation.
Yes. The unit provides taps at 2 at +2.5% FCAN and 4 at -2.5% FCBN, enabling practical voltage regulation to compensate for feeder fluctuations without external tap-changing gear. This aids commissioning and maintains tighter downstream tolerances for critical equipment.
