FAQs
Yes. The unit integrates a Primary MCCB (LGE3400FAGC) and uses a 280BPB wiring connection, simplifying protection coordination and minimizing wiring complexity in standard control panels and MCCs.
Key ratings include 225 kVA, three-phase, primary 480 V, secondary 208Y/120 V, 60 Hz, 80 °C rise, copper windings, and a 945SD frame. It uses a copper windings construction with a 318 °C insulation class to support reliable operation.
Best suited for control panels, motor control centers, and plants requiring reliable 208Y/120 V control power from a 480 V service. Its NEMA 2 enclosure and WS69 weather shield make it suitable for indoor environments with modest protection needs.
The transformer is UL Listed and complies with DOE 2016 efficiency requirements, along with 10 CFR Part 431 (2016 Efficient) notes, aligning with modern energy and safety regulations for industrial facilities.
Consider space requirements from the 33.5 in depth, 74.8 in height, and 42.18 in width profile, plus the integrated protection and copper windings for reduced maintenance. The WS69 weather shield and NEMA 2 enclosure help minimize enclosure upkeep, lowering long-term costs.
