The calculation of t is valid for values that have exceeded the activation threshold of the protection.
t
(2)
Valid tolerances with release energized in service conditions or with the auxiliary, tripping time = 100 ms, temperature and currents within operating
limits. If the conditions are not guaranteed, the tolerance of the tripping time becomes ± 20%.
(3)
For the startup functions, the specified time is the period for which the protection with the different threshold remains active, calculated from when
the startup threshold is exceeded.
