FAQs
MV48M28F12CUDNEEES is a three-phase transformer with a 480 V primary and 208Y/120 V secondary, designed for marine-duty environments. It uses a 916A frame and a 283B112M wiring connection, enabling straightforward panel mounting and terminations. Plan for adequate ventilation, weather protection (WS19), and room for the 112.5 kVA load, while accounting for the +2.5% / -2.5% tap settings to compensate line drop across longer runs.
Key specs include a 112.5 kVA rating, 60 Hz frequency, 480 V primary, and 208Y/120 V secondary. The transformer uses copper windings and has a 115 °C rise rating with a rugged marine-duty DT-3 construction. It supports a flexible tap range (+2.5% / -2.5%) and carries UL Listed certification, ensuring reliable operation and regulatory alignment in demanding facilities.
Yes. This model is explicitly described as a marine-duty, three-phase ventilated transformer with DT-3 design, optimized for harsh marine environments. It includes weather protection (WS19) and a robust copper-winding build, making it suitable for offshore and coastal installations where reliable power distribution and resistance to environmental factors are critical.
The MV48M28F12CUDNEEES carries UL Listed certification, a key indicator of safety and compliance in North American electrical installations.
