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.

The supply voltage may deviate from the rated supply voltage specified in the table by
max. -15% to +10%.

Closing solenoid (-Y9) 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.
