FAQs
Yes. This unit is designed for three-phase operation with a 480 V primary and a 208Y/120 V secondary, making it suitable for distribution panels, motor control centers, and machine rooms that require stepped-down voltage without adding separate protective assemblies.
It integrates primary and secondary MCCBs (JGE3250FAGC on the primary and FR942SD on the secondary) into a single, compact package, reducing wiring, improving protection coordination, and simplifying maintenance workflows in MCC assemblies.
The unit is UL Listed and complies with DOE 2016 Efficient guidelines, along with 10 CFR Part 431 efficiency requirements. These certifications support regulatory compliance, energy efficiency programs, and green initiative goals in industrial facilities.
Voltage taps are provided: 2 taps at +2.5% and 4 taps at -2.5%, enabling precise regulation to maintain downstream equipment performance and protect sensitive controls from voltage drift in fluctuating power environments.
Plan for upright, floor or wall mounting in a controlled environment with a NEMA 2 enclosure. Ensure copper windings and insulation ratings align with your thermal profile (150 °C rise) and budget for the integrated protection features to reduce field wiring and maintenance time.
