What is Arc Fault protection (AFDD) and how it works?

The VigiARC is an all-in-one advanced protective device against electrical risks, combining:


-    An arc fault detection device to protect from arc fault related fires
-    An overvoltage detection to protect the appliances
-    A residual current device to protect people
-    A miniature circuit breaker to protect electrical circuits

(fig 1)

An AFDD detects the characteristics of dangerous arcing.
Once it has been detected, it opens the electrical circuit to prevent a fire propagation.
This is through an electronic system, that monitors electrical parameters in real time
(current, high frequencies, voltage).

Thanks to in-built connectivity, Acti9 Active VigiARC can send data and notifications via our latest generation of gateways and the EcoStruxure Panel Server for easy diagnostics.
