Eaton Specification Sheet - X48M34B33CUEETTNON
Harmonic mitigation design reduces current distortion by filtering out harmonic components generated by nonlinear loads, improving system power factor and reducing heat losses. This translates to lower maintenance costs, longer motor life, and fewer nuisance tripping events, particularly in facilities with high non-linear load such as drives and inverters. Copper windings and an 80 °C rise rating deliver high reliability and robust performance in warm spaces or confined plant rooms, supporting longer service life and reduced cooling requirements. The transformer’s taps, +2.5% and -2.5% (2 and 4 taps respectively), enable precise voltage regulation to compensate for supply variation and loading, minimizing voltage fluctuations that can damage sensitive equipment. UL Listed and NEMA TP-1 compliant certifications, along with center-coil thermal indicators and electrostatic shielding, bolster compliance, EMI control, and safety in critical environments like data centers and hospitals. The 480 V primary and 400Y/231 V secondary in a three-phase, 60 Hz configuration offer a practical, scalable solution for modern distribution schemes, while the dry-type EE core design supports straightforward indoor installation and reduced footprint. Overall, the product combines industry-standard ratings with practical features to ease procurement, installation, and ongoing maintenance in industrial facilities.

FAQs
Begin by confirming the 480 V primary and 400Y/231 V secondary ratings and ensure the switchgear can accommodate a 300 kVA, three-phase unit. Connect the high-voltage primary to the 480 V bus, and wire the secondary to the 400Y/231 V load with the correct grounding. Utilize the device’s two taps (+2.5% and -2.5%) to fine-tune voltage under load changes. Verify center-coil temperature indicators and electrostatic shielding are intact for safe operation, and comply with UL Listed and NEMA TP-1 requirements during commissioning.
Key specifications include a 300 kVA rating, 60 Hz frequency, three-phase configuration, 480 V primary, 400Y/231 V secondary, and zero phase shift (0°). It uses copper windings and an EE dry-type core with an 80 °C rise, plus taps at +2.5% and -2.5% for voltage adjustment. It is UL Listed and NEMA TP-1 compliant, with embedded thermal indicators in the center coil to monitor operating temperature and reliability.
Yes. Its harmonic mitigating design helps manage distortion from nonlinear PV inverters and other equipment common in data centers. The 480 V to 400Y/231 V output suits many building distribution schemes, while UL Listed and NEMA TP-1 compliance support safety and regulatory requirements in critical facilities. The device’s compact dry-type EE core and copper windings offer reliable performance in indoor spaces typical of these applications.
The unit is UL Listed, satisfying recognized safety standards for electrical equipment, and NEMA TP-1 compliant, ensuring efficiency targets and performance within industry guidelines. These certifications, along with electrostatic shielding and center-coil thermal indicators, provide regulatory assurance, EMI control, and easier acceptance in regulated facilities such as healthcare, data centers, and industrial plants.
Maintenance is typically low for a dry-type transformer with copper windings, due to solid insulation and minimal cooling requirements. The embedded thermal indicators simplify thermal monitoring, and the 80 °C rise rating provides resilience in warmer spaces. ROI is enhanced by improved power quality, reduced harmonic losses, longer motor life, and fewer nuisance trips, which collectively lower maintenance costs and downtime in capital-intensive facilities.
