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.
