Eaton N48M28B30LS42 K-Factor Transformer - UL Listed
Part Number: N48M28B30LS42
Quick Summary
The Eaton N48M28B30LS42 K-Factor nonlinear ventilated transformer delivers stable power conditioning for demanding three-phase industrial systems across manufacturing floors, data centers, and process lines, where harmonic-rich loads and fluctuating voltages threaten equipment life and process precision. In practice, maintenance teams wrestle with unexpected voltage sags, excessive temperature rise, and nuisance EMI, which reduce uptime and increase spare-part consumption; this unit mitigates those pain points through robust cooling, shielding, and a fixed 80°C rise design. UL Listed certification provides immediate safety assurance for industrial deployment, while the transformer’s K-13 configuration, WS39 weather shield, and electrostatic shielding address common regulatory and EMI considerations, helping you meet site standards without compromising performance.

Eaton Specification Sheet - N48M28B30LS42
Feature — K-13 K-Factor nonlinear transformer design minimizes magnetic heating under non-linear loads common in modern manufacturing environments, delivering stable voltage profiles. Business impact — reduces thermal stress, extends service life, lowers maintenance costs when harmonics are present in motor drives and CNC equipment. Application — ideal for motor drives, power supplies, and factory lines with non-linear loads, where reliability and uptime are mission-critical; UL Listed for safety. Feature — Ventilated construction enables superior cooling at full 60 Hz loading, distributing airflow to critical hot spots and reducing hotspot risk. Business impact — maintains the 30 kVA rating without overheating, boosting uptime and process availability across demanding production lines. Application — well-suited to switchgear rooms, MCCs, and remote substations where airflow is a constraint yet high reliability is required. Feature — Aluminum windings with electrostatic shielding deliver EMI protection and corrosion resistance, supporting long service life in harsh environments. Business impact — improves reliability of nearby controls and reduces diagnostic time due to EMI interference, enabling proactive maintenance. Application — ideal for dense plant floors, control rooms, and outdoor installations using WS39 weather shield to extend protection. Feature — Tap settings: two taps at +2.5% FCAN and four taps at -2.5% FCBN for voltage regulation across fluctuating loads. Business impact — enables smoother bus voltage and compatibility with diverse distribution schemes, reducing risk of under- and over-voltage events. Application — supports critical processes, MCCs, and power distribution panels requiring tight voltage control in industrial facilities. Feature — 480 V primary, 208Y/120 V secondary, three-phase, 60 Hz, 30 kVA rating, all framed within 914D enclosure. Business impact — standard voltage levels simplify integration with existing equipment, minimizing wiring changes and lowering installation costs. Application — ideal for plant-wide AC power distribution, enabling smoother control of motors, drives, and essential auxiliaries. Feature — WS39 weathershield, electrostatic shielding, and low sound at 42 dB, enabling flexible indoor and outdoor deployment. Business impact — supports quiet operation around personnel and reduces EMI-related commissioning time. Application — outdoor installations or shielded indoor locations where sound, heat, and interference are concerns.

FAQs
Install the N48M28B30LS42 in a spacious panel or equipment room with a 29 in wide by 22 in deep by 39 in high footprint, framed in 914D. The unit weighs about 480 lb and runs on a 480 V primary with 208Y/120 V secondary at 60 Hz. Ensure proper ventilation, clearance for taps, and adherence to UL Listed installation guidelines.
Key performance specs include a 30 kVA rating, 60 Hz frequency, three-phase operation, primary voltage 480 V, secondary 208Y/120 V, and 80°C temperature rise. The device uses aluminum windings, is electrostatically shielded, and features WS39 Weathershield. Voltage taps are available at +2.5% FCAN and -2.5% FCBN to accommodate voltage swings. The frame is 914D.
Yes, the transformer supports outdoor and harsh indoor environments thanks to the WS39 weathershield and electrostatic shielding for EMI protection. Its aluminum windings and 80°C rise are designed for durable operation under typical 60 Hz industrial loads. Ensure enclosure protection and ventilation are maintained, and confirm ambient temperature and humidity conditions meet Eaton's installation guidelines.
The N48M28B30LS42 is UL Listed, confirming compliance with electrical safety standards for industrial transformers. No SIL, CE, or IP ratings are listed in the provided data, so verify site-specific certifications with Eaton or the distributor before deployment in regulated environments. Ongoing compliance is supported by the unit's 60 Hz design, 480 V primary, and shielding features that mitigate interference in sensitive equipment.
Warranty coverage includes Eaton's policy: one year from installation or eighteen months from shipment, whichever occurs first, supporting asset protection during initial usage.
