660V OPERATION VOLTAGE ATS REQUIRED

[Anmol_GP]

Hello,

We require ATS suitable for 660V AC operation voltage for one of the solar project in India.

There are 2 string Inverters which will feed as input to ATS and provide redundant supply at output.

Is there any product suitable ?

Can we use Motorized MCCB based ATS?

or Contactor based ATS scheme?

Thanks

Hello,

No problem for MCCBs, the issue is on the control at this voltage level.

What is the rated current you need ? And the control functions ? Simple voltage presence or advanced with voltage & freq tresholds ?

Do you have 230V or 400V available in the panel for auxiliary controls ?

Thanks,

Christian
