Define the purpose of the 380 V to 380 V ratio

An equal nominal voltage ratio can be reviewed for electrical isolation, but the product string does not establish phase, connection, neutral, earthing, shielding or voltage regulation. Provide the single-line diagram and isolation objective.

Check the 20 kVA load duty

Share continuous and peak load, starting current, power factor, harmonics and duty cycle. If the load includes a VFD, UPS, rectifier or other nonlinear equipment, identify it for engineering review rather than assuming suitability.

Verify winding and insulation construction

The production material field lists Copper Winding. Request conductor, insulation, winding arrangement, electrostatic shield if required, terminal and enclosure details for the quoted model.

Coordinate protection and installation

State available fault current, upstream and downstream protection, earthing, ambient temperature, altitude, ventilation, dust, humidity, clearances and cable approach. Request impedance and inrush data when needed for settings.

Confirm performance, standards and tests

Ask for model-specific losses, impedance, temperature rise, sound and dielectric test scope. IEC in the database is a reference only until the required standard edition and model-matched evidence are reviewed.

Frequently Asked Questions

The equal nominal voltages can support an isolation requirement, but final phase, connection, regulation, neutral and shielding details must be confirmed in the quoted model schedule.

Do not assume it can. Provide load current, harmonics, duty cycle, inrush and isolation or shielding requirements so the application can be reviewed.

The current record does not confirm an electrostatic shield. State whether shielding is required and verify its construction and terminal arrangement in the model documents.

It is the production material-field entry. Request the model datasheet and drawing to confirm conductor, winding arrangement, insulation and terminals.

No. State the required IEC standard and edition, then confirm that the offered model and ratings are covered by the relevant report or declaration.
