Part Number: V39M28E75XZZ
Quick Summary
The Eaton V39M28E75XZZ transformer delivers reliable three-phase distribution for industrial facilities. Engineers often struggle to maintain stable voltage and manage heat in compact spaces, leading to downtime and inefficiency. UL Recognized safety certification underpins compliance, and the open core-coil design supports robust ventilation in harsh environments. It combines aluminum windings, electrostatic shielding, and a CT12C103 frame to deliver durable, low-loss operation. With a 75 kVA rating, a 400 V primary and 208Y/120 V secondary, plus taps at ±2.5%, it scales to diverse plant needs while simplifying installation. Designed for 50–60 Hz service and a 150°C rise, it aligns with common industrial power distribution standards and long-term reliability goals.

FAQs
Install the V39M28E75XZZ into a compatible DT-3 frame using the CT12C103 mounting provisions. Use correctly rated conductors for 400 V primary and 208Y/120 V secondary, following local codes. Ensure ventilation clearance around the open core-coil assembly and connect primary and secondary leads per the labeling; observe tap settings for voltage regulation (+2.5% and -2.5%).
Key specs include a 75 kVA rating, three-phase configuration, 400 V primary, 208Y/120 V secondary, 50–60 Hz operation, aluminum windings, electrostatic shield, DT-3 design, frame CT12C103, and a 150°C rise. Voltage taps are +2.5% FCAN and -2.5% FCBN to accommodate short-term voltage variation in real-world installations.
Yes. The transformer is designed for 400 V primary and 208Y/120 V secondary, three-phase distribution at 50–60 Hz, and a 75 kVA rating. Its open-core, ventilated construction and electrostatic shield are well-suited for plant environments, delivering stable output with good fault tolerance and simplified integration into panel boards and control systems.
The V39M28E75XZZ carries UL Recognized certification, indicating compliance with essential electrical safety standards for industrial components. This simplifies procurement, risk assessment, and regulatory alignment for most North American facilities. Verify any additional regional requirements for CE or other certifications specific to your operation since those are not listed in the product data.
Maintenance focuses on ensuring clean cooling airflow, confirming terminal integrity, and periodic insulation checks to monitor moisture or contamination risks. ROI derives from reduced downtime, improved voltage regulation with tap adjustments, and durable aluminum windings plus protective shielding that extend service life, minimizing replacement frequency in high-demand industrial environments.
