FAQs
This transformer weighs about 3119 lb and measures roughly 36.23 in long, 44.2 in wide, and 75 in tall, which necessitates appropriate hoisting equipment, floor loading assessment, and clearance for ventilation. Plan for 480 V input and 208Y/120 V output wiring, with space for cooling and maintenance access. Compliance with UL Listed and NEMA TP-1 reduces field retrofit risk.
The unit is a three-phase transformer rated at 300 kVA with a 60 Hz frequency, primary voltage of 480 V, and secondary voltage of 208 Y/120 V. Taps provide +2.5% and -2.5% adjustment to accommodate voltage fluctuations. Temperature rise is 80 °C, and coil material is aluminum, supporting robust thermal performance in demanding environments.
Yes. Its K-Factor nonlinear design mitigates harmonic effects typical in high-density loads, helping protect downstream equipment. With UL Listed and NEMA TP-1 efficiency conformance, low sound (52 dB) and electrostatic shielding, it is well-suited for data centers, manufacturing floors, and process facilities requiring reliable power quality and quiet operation.
The transformer is UL Listed and NEMA TP-1 compliant, confirming safety, regulatory alignment, and efficiency standards. These certifications provide assurance for code compliance during installation, reduce risk during audits, and support warranty eligibility when paired with Eaton’s policy terms.
With electrostatic shielding, low sound operation, and robust aluminum windings in a durable 920E frame, maintenance requires periodic inspection of ventilation, connections, and insulation integrity. The 25-000 Eaton warranty and a long service life under 80 °C rise contribute to a favorable ROI by reducing downtime, extending mean time between failures, and lowering life-cycle costs.
