FAQs
Consider floor space and weight; this unit weighs about 2492 lb and uses a 919E frame, requiring a sturdy foundation and appropriate clearance for ventilation and service access. Plan for WS35 weather shielding if outdoor or semi-outdoor use and ensure adequate electrical room clearances for wiring connections (292A). Verify mounting provisions and electrical code compliance with the site’s standards and Eaton’s installation guides.
Verify a 225 kVA VA rating, 480 V primary voltage, and 208 Y/120 V secondary voltage for correct load matching. Confirm 60 Hz frequency, three-phase configuration, and tap settings of +2.5% / -2.5% to accommodate site voltage variations. Check insulation and copper/aluminum coil considerations, and ensure wiring conductor sizing aligns with 292A connection and frame 919E constraints.
Yes, it is designed with WS35 weather protection and fungus-proof construction suitable for challenging environments. The electrostatic shielding further improves EMI performance, making it appropriate for facilities with high ambient humidity or contamination. When outdoor use is planned, confirm enclosure integrity and ventilation align with local codes and site conditions.
Certifications are listed as ‘Contact Manufacturer’ for this model. In practice, you should request official certificates or test reports from Eaton to confirm CE, IP, SIL, or other region-specific approvals. Use the manufacturer’s documentation and the official spec sheet to verify compliance and ensure the unit meets your regulatory and safety requirements.
The 225 kVA nonlinear ventilated transformer offers high efficiency with NEMA TP-1 alignment and fungus-proof design, which reduces energy loss and maintenance intervals in humid environments. Its robust 115 °C rise rating supports reliable operation under heavier loads, while the one-year warranty (or 18 months from shipment) provides a clear depreciation period. Consider the total cost of ownership improvements from reduced downtime and longer service life when evaluating ROI.
