FAQs
Plan for a secure three-phase mounting footprint compatible with the 912B frame, with enough clearance for ventilation and wiring access. Connect the primary to 480 V and the secondary to 480Y/277 V according to the nameplate, using aluminum windings and proper grounding. If outdoor exposure is expected, consider WS38 weather shielding and follow UL Listed installation guidelines to maintain safety and performance.
Key specs include a 30 kVA rating, 60 Hz frequency, 480 V primary, 480Y/277 V secondary, and a temperature rise of 80 °C. Tap settings of 2 at +2.5% and 4 at -2.5% FCAN/FCBN enable voltage tuning. The device uses aluminum windings, an electrostatic shield, and a 912B frame to balance efficiency with reliability in harmonic-rich environments.
Yes. The three-phase 30 kVA capability, K-Factor nonlinear design, and ventilated construction suit data centers and manufacturing floors where harmonics and tight voltage control matter. Aluminum windings reduce weight, shielding minimizes EMI, and the WS38 weather shield supports durable operation in varied environments, aiding uptime and regulator compliance.
This transformer is UL Listed, indicating safety compliance for electrical equipment. The UL listing helps meet regulatory requirements during procurement and installation, reducing risk during audits and ensuring compatibility with common safety standards across facilities that rely on standardized power infrastructure.
Warranty follows Eaton Selling Policy 25-000: one year from installation or 18 months from shipment, whichever comes first. Routine maintenance focuses on ensuring proper ventilation, secure connections for the primary and secondary circuits, and periodic inspection of the Shield and WS38 enclosure to preserve EMI containment and environmental protection.
