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.
The interval of time between the initiation (command) of the closing operation and the
instant when the contacts touch in all poles.
The interval of time between the initiation (command) of the opening operation and the
instant when the contacts separate in all poles.
The interval of time from the first initiation of an arc and the instant of final arc extinction in
all poles.
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).
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.

The closing solenoid closes the circuit-breaker electrically. The closing command is executed
by application of an auxiliary voltage (AC or DC, depending on the design option). After
closing, the closing solenoid is de-energized internally.
