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 motor operating mechanism of the circuit-breaker is appropriate for auto-reclosing.
