Product Overview
Designed for commercial buildings, light industrial facilities and retrofit electrical rooms, this 150kVA three phase dry type isolation transformer converts 600V Delta primary power to 208Y/120V Wye-N secondary distribution. The secondary configuration supports both 208V three-phase equipment and 120V line-to-neutral branch circuits, making it suitable for facility power distribution, equipment panels and building service applications.
Built with a NEMA 3R enclosure, ANN cooling, aluminum windings and a 220°C insulation class, the transformer is suitable for indoor or sheltered installation points where dry-type, oil-free equipment is preferred. The primary tap range from 630V to 540V helps match site voltage conditions while maintaining practical flexibility for North American low-voltage distribution projects.
