Industrial 423-D005-001 Transformer

ALFA 423-D005-001 is a 550 kVA three‑phase dry‑type transformer with a 460 V delta primary and a 460Y/266 V secondary (460 V line‑to‑line on the LV side; 266 V line‑to‑neutral). Designed for indoor use in industrial facilities (NEMA 1 enclosure) and rated for 50/60 Hz operation, it provides a reliable means to supply equipment from a 460 V source while delivering 266 V per phase on the LV side. The 460 V delta to 460Y/266 V configuration is a common arrangement for distributing power to medium‑voltage loads in manufacturing and processing environments. As a dry‑type unit, it is suitable for installation in indoor electrical rooms or equipment spaces where enclosure type and ventilation meet standard building codes. With a 550 kVA rating, this transformer handles substantial load demands while maintaining voltage regulation across the windings, making it a robust solution for industrial power distribution needs.
