FAQs
This unit weighs about 1200 lb and measures 31.5 in by 51 in by 34.5 in. Plan for adequate clearance, ventilation, and access for wiring. Wiring connection is 283B, and the frame is 943, which informs mounting and enclosure requirements. Include proper lifting gear and adherence to UL Listed installation practices to maintain safety and performance.
The transformer provides 112.50 kVA (112.5 KVA), is three-phase, with a primary voltage of 480 V and a secondary voltage of 208Y/120 V. It features a 150 °C rise, K-Factor nonlinear design (K13), and DOE2016 Efficient compliance, all of which influence sizing, cooling, and load management decisions.
Yes. With 112.5 kVA capacity, 480 V to 208Y/120 V distribution, and energy-efficient DOE2016 compliance, it suits control panels, machine centers, and data centers that require reliable, scalable power delivery while controlling energy costs and thermal load within cabinets and rooms.
The N48M28T1221I4 carries UL Listed certification and DOE2016 Efficient compliance. UL Listing confirms safety standards are met, while DOE2016 efficiency reduces no-load and load losses, improving operating costs and contributing to regulatory and environmental program requirements for industrial facilities.
Expect lower lifecycle costs due to DOE2016 efficiency and reduced thermal stress from the ventilated design, translating into energy savings and potentially fewer cooling-related outages. The robust K-Factor construction also supports longer mean time between failures (MTBF) in demanding environments, minimizing maintenance downtime and replacement risk.
