- Convert current based on 380V
- Overwrite Selection Tiers
- Available for all series
For domestic low-voltage grid standards, 3 kW and below use Y connection, while over 3 kW uses Δ connection, suitable for most factory distribution scenarios.

Rated current for this voltage condition is listed in the parameter table; verify against your site's power system during selection.
For the same model, output power, speed, efficiency, power factor, and torque remain constant regardless of voltage; only the rated current is adjusted using I = IN × 380 / U. Dual-voltage motor models (380/660V and 660/1140V) are switched via jumpers in the terminal box. The 1140V model is designed for high-voltage supply in underground coal mines and requires verification that its explosion-proof certification covers the application. Variable frequency drives (VFDs) are categorized by supply voltage; specify the site supply voltage, phase count, and frequency at the time of order.
