Operating times, contacts
The time indications in the following table refer to the application of the switchgear in
accordance with IEC 60721-3-3 Class 3K4. If the switchgear is operated beyond this range, the
indicated times may deviate.

1)
For operation of the switchgear beyond the range defined by IEC 60721-3-3 Class 3K4, a minimum command duration of 100 ms is
recommended.
Closing time:
The interval of time between the initiation (command) of the closing operation
and the instant when the contacts touch in all poles.
Opening time:
The interval of time between the initiation (command) of the opening operation
and the instant when the contacts separate in all poles.
Arcing time:
The interval of time from the first initiation of an arc and the instant of final arc
extinction in all poles.
Break time:
The interval of time between the initiation (command) of the opening operation
and the instant of final arc extinction in the last-pole-to-clear (= opening time and arcing time).
Close-open contact time:
The interval of time - in a make-break operating cycle - between the
instant when the contacts touch in the first pole in the closing process, and the instant when the
contacts separate in all poles in the subsequent opening process.
