Frequently Asked Questions

What AC-3 current range is covered by the listed ZS3TF models?

The 17 listed models cover 9A to 400A AC-3 rated operational current at 380V.

How should I select a ZS3TF model?

Select by the required AC-3 current at 380V and corresponding motor output, then provide the required coil/control voltage and auxiliary contact arrangement for configuration confirmation.

What supply frequency is listed for the ZS3TF family?

The supplier technical catalog lists 50/60Hz.

Are all auxiliary contact arrangements mapped to every model?

No. The catalog states arrangements up to 2NO + 2NC at family level, but the exact arrangement is not mapped to every model and must be confirmed for the selected configuration.
