Sizing & Application

The Delta DC6225V is a 225 KVA, 3-phase step-down transformer rated 600V primary to 120/208V secondary, housed in a NEMA 3R enclosure for outdoor or semi-protected installations. At 225 KVA, it is well-suited for commercial and light industrial applications — including rooftop mechanical rooms, parking structures, and outdoor distribution points — where a weatherproof enclosure and high-capacity step-down from a 600V service are required. Confirm your load calculations, feeder sizing, and mounting requirements with our team to ensure this unit is the right fit for your project.

The DC6225V steps down from a 600V primary to a 120/208V secondary, delivering a standard 3-phase, 4-wire wye output. This makes it suitable for powering typical commercial 208V 3-phase equipment (HVAC, motors, panels) as well as 120V single-phase branch loads from the same transformer. At 225 KVA, it can support substantial commercial load — contact us to review your load schedule and confirm suitability.

Yes — the NEMA 3R enclosure is specifically designed for outdoor use. NEMA 3R provides protection against falling rain, sleet, and ice formation, making the DC6225V suitable for rooftop installations, outdoor switchgear lineups, or covered exterior locations. It is not rated for full submersion or direct water spray (NEMA 3 or 4 applications). Always verify local code and clearance requirements for your specific installation.
