Specifications:
The EVI CDTC0045RHA6XXBA is a 45 kVA, 3-phase dry-type low-voltage distribution/isolation transformer that steps down a 480V primary voltage to a 208Y/120V secondary voltage.
- Primary Voltage: 480V (3-phase)
- Secondary Voltage: 208Y/120V (3-phase wye with neutral, providing 208V 3-phase and 120V single-phase)
- Type: Dry-type transformer (no cooling oil required)
- Application: Commercial and industrial facilities to power 208V machinery and 120V lighting, receptacles, or control circuits from a 480V service.
Electrical Sizing Reference (45 kVA at 480V)
- Primary Full-Load Current: Approximately 54.1A to 54.2A
- Secondary Full-Load Current (at 208V/120V): Approximately 124.9A
- Typical Overcurrent Protection (NEC 450.3 / 125% rule): Often paired with a 70A primary breaker (or a 60A breaker depending on specific load conditions and local electrical codes)
