3-Phase Isolation Transformer 3 x 400V -> 3 x 208V + N
Our three-phase transformer 3 × 400 VAC → 3 × 208 VAC + Neutral is specifically designed to power North American equipment operating on a 208V three-phase network in Europe.
This voltage, very common in the United States and Canada, cannot be obtained directly from a European 400/230V network: a 400V → 208V step-down transformer is therefore essential.
Thanks to its robust construction, high efficiency and perfectly balanced three-phase winding, this 3 × 208V three-phase transformer guarantees stable voltage, reinforced isolation, and power perfectly adapted to American machines, air conditioners, servers, or industrial equipment.
- Input voltage: 3 x 400 VAC
- Output voltage: 3 x 208 VAC + N
- IP23 enclosure finish
- Primary wiring: Delta △
- Secondary wiring: Star ★ + N
- Available wiring: DYN11; YND; ZZYN (extra charge)
Functions and uses of our three-phase isolation transformer
This transformer is designed to transform 3 x 400 V into 3 x 208 V, electrically isolate an installation from the power grid and/or generate a neutral point when it is not available.
It is particularly suitable for industrial, commercial or automation installations requiring galvanic separation to improve the safety and reliability of the network.
This model is used to power all machines designed for 208 VAC three-phase:
- HVAC and air conditioning equipment (USA/Canada)
- Rooftop units (TRANE, YORK, LENNOX, CARRIER)
- 208 V cooling units and compressors
- Commercial heat pumps
- Elevators & motor drives
- Hydraulic or electric elevator motors
- American lifting platforms
- Machine tools and workshops
- American lathes, milling machines, CNC
- Industrial printers & packaging machines
- Three-phase compressors
- Professional kitchens & catering
- 208 V Ovens (Hobart, Duke, American Range)
- Industrial deep fryers
- Commercial dishwashers
- Datacenters and servers
- 208 V Three-phase UPS
- 208 V PDUs
- Server racks designed for the North American grid
If you are using a machine from the United States or Canada in Europe, it will 99% of the time require a 3 × 208V three-phase transformer.
This model is therefore the ideal solution.
Technical advantages of the three-phase isolation transformer
- Reduction of harmonics and electromagnetic interference, for more stable operation of your equipment.
- Elimination of residual voltages on the neutral: in this case, the neutral must be grounded to ensure optimal potential stability.
- Total galvanic isolation between primary and secondary, limiting the risk of back-feeding or disturbance.
- Robust and ventilated construction in an IP23 IK08 metal enclosure, suitable for demanding environments.
- Customisation possible: power rating, voltage, adjustment taps, mounting accessories, or custom enclosures. Access our configurator >> Transfo Creator Three-Phase
Ultra-fast shipping times for the three-phase range

Coupling of the 400V 208V + N transformer
The standard coupling for our 400 208 + N three-phase transformer is DYN11 (delta on the primary, star + neutral on the secondary). Other couplings are possible according to your needs, please contact us for any wiring different from DYN11.
