FAQs
Install on a floor or wall, upright orientation. The unit weighs 661 lb with dimensions of 24 in L, 30.5 in W, and 43 in H, requiring suitable structural support and access for service. Plan for copper windings and NEMA 2 enclosure to ensure proper ventilation and protection in typical industrial rooms.
The transformer provides a 208 V primary and a 208Y/120 V secondary in a three-phase configuration, 45 kVA rating. This supports typical facility power distribution where a single source feeds 208 V equipment and 120 V auxiliary loads from the same transformer.
It complies with DOE 2016 Efficient standards and is UL Listed. The catalog notes reference 10 CFR Part 431 Efficient, aligning with regulatory energy requirements for commercial and industrial facilities.
K-Factor 13 indicates a design optimized for nonlinear loading with reduced harmonic distortion, improving power quality and reducing overheating risk in strained electrical rooms, which translates to longer equipment life and fewer nuisance trips.
Benefits include DOE 2016 efficiency, UL safety certification, and reduced cooling energy due to lower heat output. Coupled with reliable copper windings and shielded construction, the unit lowers operating costs, minimizes maintenance, and supports faster compliance reporting for industrial plants.
