Guideline values for function times at the rated supply voltage:
Closing time
Opening time
Arcing time (at 50 Hz)
Total break time
Minimum command time on closing
Minimum command time on opening
1)
When the operating voltage is lower than the rated voltage, the same values apply as for rated voltage. Higher values on request.
2)
If the activating relay contact cannot itself interrupt the release coil current
