FAQs
Plan for a 3-phase installation with a 480 V delta primary to 208Y/120 V secondary configuration. Mount in a location protected from moisture and dust, using the NEMA 2 enclosure and FR940 frame. Ensure adequate clearance for cooling, access to taps, and compliance with 10 CFR Part 431 requirements. Use compatible switchgear and follow Eaton’s mounting guidelines for best performance and serviceability.
It is DOE2016 Efficient and UL Listed, specifically designed as a solar duty rated transformer. The aluminum coil provides good heat dissipation, and the 60 Hz, three-phase design supports reliable conversion for PV inverters and balance-of-system components. Its 45 KVA rating matches mid-size solar arrays, enabling efficient energy transfer with minimal losses.
Yes. The transformer is specified for a 480 V delta primary and a 208Y/120 V secondary, delivering a stable stepped-down voltage suitable for controls, MCCs, and distribution panels. Ensure wiring methods, tap settings, and protective devices accommodate the ±2.5% taps to maintain voltage within tolerance at varying loads.
The unit is UL Listed and DOE2016 Efficient, with a NEMA 2 enclosure suitable for indoor or sheltered outdoor locations. Catalog notes reference 10 CFR Part 431 (2016) Efficient, supporting compliance for energy efficiency programs and regulatory audits in commercial and industrial facilities.
By delivering DOE 2016 efficiency, the transformer reduces no-load and load losses, lowering energy costs over its lifecycle. Aluminum windings improve heat management, enabling stable voltage regulation and extended equipment life. In practice, you’ll see lower cooling demand, reduced maintenance intervals, and improved uptime for solar inverters and downstream power distribution.
