FAQs
Install the X48M28F12TCUEENON in a suitable indoor or sheltered location with adequate ventilation for its 115 °C rise. Use the 200X wiring connection and connect primary to 480 V three-phase supply, with 208Y/120 V secondary. Confirm proper torque on copper windings and taps: +2.5% at two positions and -2.5% at four positions to match site voltage.
By employing copper windings and an electrostatically shielded design, the transformer reduces harmonic currents entering sensitive equipment. Its NEMA TP-1 efficient profile, plus calibration taps, minimizes distortion and heat. In PV and mixed-load environments, expect improved power factor, lower maintenance costs, and longer equipment life, delivering measurable efficiency gains without sacrificing reliability.
Designed as a dry-type transformer with WS34 weather shield, it is well-suited for indoor and semi-outdoor installations where environmental exposure is a concern. The unit’s electrostatic shielding and a built-in thermal indicator support safe operation and proactive maintenance, while UL Listed and NEMA TP-1 compliance ease integration into existing building codes.
UL Listed and NEMA TP-1 compliant, the X48M28F12TCUEENON is also cataloged as NEMA TP-1 efficient. These certifications ensure code compliance, safer operation, and reduced utility penalties in many jurisdictions. The product ships with Eaton’s warranty terms, and the copper-wound, shielded construction supports long service life in demanding industrial environments. This aligns with strict electrical codes and helps procurement teams simplify audits.
Though initial cost reflects robust, durable construction, the X48M28F12TCUEENON reduces downstream maintenance and energy losses from harmonics. Copper windings, thermal indicator, and electrostatic shielding enable predictive maintenance and fewer unexpected outages. With a 112.5 kVA rating and 60 Hz operation, facilities see improved uptime, longer asset life, and lower total cost of ownership.
