VT measurement from 0 V up to 800 VAC (300 VAC for some order options)
CT measurement always with 1 A and 5 A
Plausibility verification intelligence
Optimized functional overview by hiding unused functions, parameter and assignments

Highly Selective, high speed detection of faulty cables/lines.
Enabling uninterrupted power supply to facility like Airports, Data Centers, Waste Water Stations,…)
On redundant fed HV/MV rings architectures, faulty lines can be switched off with highest speed without any dark time for the rest of the facility.
Making time and current grading obsolete. Don’t need to wait for timers or delays of upstream or downstream breakers.
