Section 535.3 of IEC 60364-5-53:2019 vs Section 9.2 of Ecodial manual

The requirements to achieve selectivity between residual current protective devices in series, as per Section 535.3 of IEC 60364-5-53:2019 differ from that stated in Section 9.2 of Ecodial manual

Hello Mohammad,

Thanks for bringing this point to the Forum.

The terminologies are different at these documents.

• The standard suggests about the difference between the “residual operating current (In)”
• Whereas the help file document considers the “sensitivity (IAn)”

However, Ecodial ensures the selectivity of the RCD based on the sensitivity.
