10.2 Technical data
Circuit-breakers for fixed installation
10.2.1 Performance data and weights
Guideline values for function times:
Closing time ca. 45…60 ms
Opening time ca. 35…50 ms
Arcing time (at 50 Hz) ≤ 15 ms
Break time ≤ 60 ms
Minimum command time on closing 20 ms
Minimum command time on opening 20 ms
1)
At operating voltages lower than the rated voltage, the same values fundamentally apply as for the rated voltage. Higher values on request.
