FAQs
Consider mounting space and the 23.42 in x 28.22 in x 48.56 in footprint, weight of 768 lb, and the 916A frame. Plan for WS19 weather shield placement for outdoor or rugged indoor environments, plus ensure proper ventilation for the 150 °C rise. Verify taps (+2.5% and -2.5%) are configured to match on-site voltage, and confirm UL Listed and NEMA TP-1 compliance are documented in the project files.
Key specs include a 75 kVA three-phase rating, primary 208 V, secondary 480Y/277 V, 60 Hz frequency, 2 taps at +2.5% and 4 taps at -2.5%, aluminum coil, and frame 916A. Insulation system rated at 200 °C with a 150 °C temperature rise, and the unit is UL Listed and NEMA TP-1 compliant and efficient.
Yes. The transformer uses WS19 weather shielding and a ventilated design, enhancing durability in outdoor or harsh indoor environments. Its NEMA TP-1 efficient rating and UL Listed certification further support safe outdoor operation, provided it is installed with appropriate clearance and protection per Eaton’s guidelines.
Ideal for industrial power distribution in manufacturing lines, data centers, and outdoor substations. With 208 V to 480Y/277 V transformation, it supports equipment requiring multiple voltage levels, while the taps and robust insulation enable reliable operation under variable loads and ambient conditions.
