FAQs
Yes. The transformer is designed for a 480 V primary and a 208Y/120 V secondary, three-phase operation, and ships in a floor-mounted NEMA 2 enclosure suitable for standard industrial environments. Wiring connection is specified as 283B, facilitating straightforward integration into existing panels or distribution buses.
This unit is UL Listed and complies with DOE 2016 Efficient standards, including 10 CFR Part 431 (2016) Efficient guidelines. These certifications signal adherence to electrical safety, energy-performance requirements, and regulatory expectations, simplifying procurement and audit processes while supporting energy-management goals.
Plan for floor mounting in a secure, accessible location with adequate clearance around the 2692 lb unit. Use the NEMA 2 enclosure to minimize dust ingress, ensure proper vibration isolation, and allow service access. Consider wiring distance to load centers and compatibility with 283B wiring connections to optimize startup and maintenance time.
K-Factor 13 indicates enhanced protection against harmonics generated by non-linear loads such as VFDs and switching equipment. This results in reduced overheating, better voltage regulation, and lower cooling requirements, which translates to improved reliability and potential energy savings in harmonics-heavy installations.
DOE 2016 efficiency reduces core and copper losses compared with older designs, delivering lower standby and running losses. In facilities with continuous loads or harmonic-rich profiles, this can shorten payback periods through energy cost reductions, lower cooling loads, and extended equipment life, while meeting regulatory and sustainability targets.
