Eaton N48M47B75EE Transformer K-Factor Nonlinear UL Listed
Part Number: N48M47B75EE
Quick Summary
The Eaton N48M47B75EE transformer is a K-Factor nonlinear ventilated transformer for data centers and industrial plants. Engineers often struggle with voltage stability, harmonics, and space constraints in LV distribution. UL Listed, NEMA TP-1 compliant, and electrostatically shielded construction support compliance and reliability. Rated for 75 kVA three-phase service with 480 V primary and 480Y/277 V secondary, it supports flexible tap settings. The dual taps at +2.5% and -2.5% enable quick voltage adjustment on site, reducing commissioning time. Electrostatically shielded construction minimizes EMI on sensitive equipment, supporting compliance with stringent electrical safety standards. UL Listed certification and NEMA TP-1 efficiency notes aid procurement teams in meeting regulatory buying policies. By integrating with Eaton's transformer family, installation is streamlined through standardized mounting, protective devices, and documented specs.

FAQs
The N48M47B75EE uses a standard three‑phase transformer footprint with aluminum coil construction and electrostatic shielding, designed to mount in typical electrical enclosures. Ensure adequate clearance for cooling and access to taps at +2.5% and -2.5%. Confirm cabinet space for 480 V conductors, add proper protective devices, and verify UL Listed and NEMA TP‑1 compliance for field installations.
Key specs include a 75 kVA three‑phase rating, 480 V primary, 480Y/277 V secondary, 60 Hz frequency, and an 80 °C rise with taps at +2.5% and -2.5%. These values drive transformer sizing, cable sizing, and protective coordination. Designers can plan feeder protection, switchgear interfaces, and harmonic mitigation strategies around these ratings to meet reliability and efficiency goals.
Yes. The N48M47B75EE is designed for clean power delivery to sensitive equipment, with electrostatic shielding reducing EMI and UL/NEMA TP‑1 compliance supporting critical environments. Its 75 kVA rating and 480Y/277 V secondary align with typical IT loads and UPS interfaces. For data centers, pair with proper rack cooling, cable management, and rack‑level power distribution units.
Certifications include UL Listed and NEMA TP‑1 compliant notes, along with catalog notes on efficiency. This helps procurement meet regulatory and energy performance specifications, simplify supplier qualification, and reduce risk in audits. The electrostatic shielding and rigorous documentation support EMI/EMC, safety, and warranty coverage across Eaton’s transformer family.
Maintenance considerations include routine thermal monitoring, tapping verification, and adherence to Eaton warranty terms (one year from installation or 18 months from shipment). The K‑Factor nonlinear design and high‑efficiency NEMA TP‑1 profile help lower energy losses and cooling costs, improving uptime and total cost of ownership for mid‑range power distribution.
