When the relay works with more restrictive conditions (0.2 A minimum value to be operative) the
tripping time is 1200 ms. This time decreases with the current and it stabilizes at 8 amperes with
a tripping time equal to 105 miliseconds. From this value onwards the tripping time will maintain
equal to 105 miliseconds,
When the relay works with more restrictive conditions (0.1 A in three phases-minimum value
to be operative) the tripping time is 970 ms. This time decreases with the current and it
stabilizes at 5 amperes with a tripping time equal to 60 miliseconds. From this value onwards
the tripping time will maintain equal to 60 miliseconds,
