Sorry for the late answer, busy days 
The system is called Eaton ARCON
Found a video in English: http://bcove.me/zbhvhktn
I´m just copy-pasting from their site as I don´t know in detail much about the system, just how it works in general.
They also have a site for the system: http://www.eaton.eu/Europe/Electrical/ProductsServices/PowerDistribution/ARCON/index.htm#tabs-1
Some technical details from the Eaton site:
- System arc fault quenching time < 2 ms
- Detection of arc faults from 3 kA arc fault current
- Current capacity of the quenching device 65 kA, 500 ms, or 100 kA, 150 ms at 725 V as well as 150 kA, 200 ms at 440 V
- Almost complete self-monitoring of the arc fault protection system
What´s your job as you seem to know about these things? Have you ever made anything job-related in blender?
