FAQs
Plan for a frame 916A footprint and a 1132 lb weight. Ensure proper clearance for ventilation and access to the 480 V primary and 208Y/120 V secondary connections. Use the two taps at +2.5% FCAN and four taps at -2.5% FCBN to regulate voltage, and accommodate the electrostatic shield and WS19 weather shield where outdoor or harsh environments are possible.
The unit delivers 75 kVA at 60 Hz in a three-phase configuration, with a 480 V primary and 208Y/120 V secondary. It features aluminum windings, an 80 °C rise, and a K-13 design for nonlinear loading. Tap changes ±2.5% enable fine voltage adjustment. Noise is rated at 45 dB, and it includes an electrostatic shield.
Yes, it is suitable for rugged industrial environments where reliable distribution and controlled noise are important. The WS19 weather shield expands outdoor applicability, while the low noise level helps meet workspace acoustic requirements. Verify regional certifications if CE or IP ratings are mandated by local codes.
The transformer carries UL Listed certification for safety compliance. It is supported by Eaton’s warranty policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first, aiding total-cost-of-ownership planning.
Expect reliable operation with aluminum windings that resist corrosion and contribute to efficient heat management. Regular visual inspections, insulation checks, and periodic load monitoring help sustain performance. The 75 kVA rating supports scalable loads, potentially reducing the need for early replacement and minimizing lifecycle costs.
