TIME DEFINITION
CLOSING TIME : Interval of time between energizing the closing circuit and the instant when the contacts
touch in all poles.
OPENING TIME : Interval of time between the instant of energizing the opening release and the instant when
the arcing contacts have separated in all poles (or simulator contacts controled by the dummy load).
OPEN-CLOSE TIME : Interval of time between the instant when the arcing contacts have separated in all
poles and the instant when the contacts touch in the first pôle during a reclosing operation (reclosing : the
equipment is automatically reclosed after a predetermined interval of time -195 ms-).
CLOSE OPEN TIME : Interval of time between the instant when the contacts touch in the first pole during a
closing operation, and the instant when the arcing contacts have separated in all poles during the subsequent
opening operation (the opening release is energizing when the contacts touch in the first pole during the
closing operation).
DEVIATION BETWEEN CHAMBERS OF THE SAME POLE : For the same operation maximum deviation
between the instants when the chambers contacts touch during the closing operation and maximum deviation
between the instants when the chambers contacts are separated during the opening operation.
DEVIATION BETWEEN POLES : For the same operation maximum deviation between the instants when the
poles contacts touch during the closing operation and maximum deviation between the instants when the
pales contacts are separated during the opening operation.
In the case of multichambers poles, the pole is considered closed when the last chamber is closed and it is
considered opened when the first chamber is opened.
RESISTOR INSERTION TIME : during a closing operation, interval of time between the instant when the
arcing contacts are touching and the instant when the inseror contacts are touching (resistance short-
circuited).
Note : the closing time according the IEC standard for circuit-breakers with switching resistors is equal to the
sum of the closing time and resistor insertion time as défined above.
