Eaton Specification Sheet - N48M28B30CULS42
Feature: K-Factor nonlinear ventilated design helps manage harmonic currents in modern facilities, reducing overheating and extending transformer life. Business Impact: Improves system reliability and decreases maintenance needs in plants with variable and harmonic-rich loads. Application: Ideal for manufacturing lines, motor drives, and robotics in heavy industrial environments. Paragraph continues with emphasis on efficiency gains and EMI control. The transformer’s 30 kVA rating provides robust headroom for startup surges and peak loads, supporting downstream equipment without voltage sags. Application: Suitable for data centers and process control rooms where stable voltage is critical. Tap changes offer voltage regulation to maintain output within tight tolerances, reducing equipment stress and improving process consistency. Copper windings with electrostatic shielding deliver better conductivity and EMI suppression, enabling closer equipment spacing and easier code-compliant installation. Weathershield WS38 and low noise 42 dB operation minimize environmental impact in outdoor or semi-exposed installations. Frame 912B with compact footprint supports enclosure-based deployments in space-constrained electrical rooms, while an 80°C rise rating provides thermal margin during peak demand. UL Listed certification and Eaton warranty support procurement, installation, and ongoing maintenance, delivering predictable total cost of ownership and improved ROI for industrial power distribution.

FAQs
The N48M28B30CULS42 uses the 912B frame with a footprint suitable for standard electrical enclosures. Its dimensions (approximately 16.5 in L, 23 in W, 30 in H) and weight (about 432 lb) help determine rack or enclosure fit. For outdoor or harsh environments, the WS38 weather shield supports outdoor or semi-exposed installations, and the unit’s shielded construction aids EMI compliance.
This transformer is a three-phase, 30 kVA unit with a 480 V primary and a 208Y/120 V secondary. It operates at 60 Hz, uses copper windings, and includes an electrostatic shield for EMI control, meeting typical industrial distribution requirements.
Yes. Its K-Factor nonlinear design handles harmonic-rich environments common in data centers, motor drives, and processing plants. The 80 °C rise rating provides thermal margin for peak loading, while the low sound (42 dB) and UL Listed certification support compliant, space-efficient deployment in busy industrial facilities.
The N48M28B30CULS42 is UL Listed, indicating safety compliance. The unit also features electrostatic shielding for EMI control and a low sound profile, with a documented 42 dB sound level in catalog notes, supporting regulatory and workplace noise considerations.
Copper windings and robust frame design reduce thermal and mechanical wear, which lowers maintenance intervals. The 80 °C rise rating allows reliable operation under peak loads, reducing downtime. A standard Eaton warranty (one year from installation or 18 months from shipment) provides financial protection during early operation and supports predictable ROI in power distribution projects.
