FAQs
Begin with a compliant NEMA 3R enclosure and a vibration-damped mounting base. Connect the primary to 200 V supply and the secondary to 208Y/120 V as labeled. Use the two -5% FCBN taps if the supply voltage requires adjustment, and ensure proper grounding. Seal gaskets and verify UL listing compliance before power-up. Finally, perform a standard insulation and continuity check per Eaton installation guidelines.
The transformer is rated for 9 kVA at 60 Hz in a three-phase configuration. The primary voltage is 200 V, with a secondary of 208Y/120 V. It includes two taps at -5% FCBN for voltage adjustment and has a 115 °C rise rating. Winding material is aluminum, and the unit is UL Listed for safety and reliability.
Yes. The Y72G28T09 uses a NEMA 3R enclosure and is designed for indoor-outdoor service, enabling installation in sheltered outdoor locations or transition spaces without extra weatherproofing. For direct exposure, provide adequate shade or housing to maintain insulation and reduce temperature rise during peak loading.
This transformer carries UL Listed certification and is built with a NEMA 3R enclosure suitable for indoor-outdoor use. The combination ensures safety compliance, rugged environmental performance, and suitability for standard industrial power distribution applications in mixed environments.
The Y72G28T09 comes with Eaton’s warranty policy: one year from the installation date or eighteen months from shipment, whichever occurs first. Regular maintenance should focus on ensuring proper cooling, checking tap settings if voltage drift occurs, and periodic inspection of connections to minimize fault-induced downtime and extend service life.
