Siemens 3F3Y112FC Dry Type Transformer Outdoor

Siemens 3F3Y112FC is a 112.5 kVA three‑phase dry‑type transformer designed for outdoor installation in a NEMA 3R ventilated enclosure. It provides a 480 V delta primary and a 208Y/120 V secondary at 60 Hz, delivering 112.5 kVA with copper windings and a 115°C rise rating. The unit weighs 885 lb and measures 38.0 in high by 29.0 in wide by 29.0 in deep, making it a compact outdoor power distribution solution for commercial or industrial facilities. Primary voltage can be adjusted via taps: two 2.5% FCAN and four 2.5% FCBN taps to accommodate supply variations while maintaining voltage within tolerance. It carries UL and cUL listings and DOE energy efficiency compliance, aligning with safety and efficiency standards for outdoor installations. Typical applications include stepping down from 480 V to 208Y/120 V for branch circuits and equipment in outdoor electrical distribution systems in commercial and light industrial environments.
