Eaton Specification Sheet - N38M37T4516AFCU
The K-Factor nonlinear ventilated design optimizes cooling and reduces both copper and core losses, delivering lower operating temperatures and improved efficiency. This translates to real energy cost savings and extended transformer life in continuous‑duty applications such as manufacturing lines and process control. Copper windings paired with 220 °C insulation enhance thermal stability and durability, enabling reliable performance in hot or congested electrical rooms, which reduces unscheduled downtime. The NEMA 2 enclosure offers rugged protection and simple floor or wall mounting, accelerating installation in crowded plant spaces and near load centers that demand compact footprints. A 2 at +2.5% and 4 at -2.5% tap sizing scheme provides precise voltage regulation to minimize downstream equipment wear and prevent voltage fluctuation damage. Fungus‑proof design and an electrostatic shield address reliability in damp environments, lowering maintenance costs and extending service intervals. With 60 Hz operation and three‑phase configuration, it integrates smoothly with standard industrial power systems, delivering consistent performance across varied loads and environments.
