Selectivity between MCCB / IC60

[LarisaFranco]

Hi

I have an example with an upstream breaker IC60 50A and dowstream IC60 10A.

Image shows selectivity up to 680A, curves do not overload as it is time current curves. Is there a curve in EcoDial where I can see the point where the two breakers overlap? only I can see now is 680A limit.

Hello Larisa,

Thanks for reaching the EcoStruxure Power Design Forum.

Selectivity for the given MCBs

At the Ecodial application, the selectivity decision of the given MCBs is considered from the “selectivity tables” provided by the business.

The curve representation does not show the curve crossing (for the partial selectivity limit).

Yes, this part of the curve is not shown at the application.

Thanks & Regards,
