Note on protections
(1)
use trip and threshold current values expressed in In for calculating t
t
(example: If = 0.8 In, I1= 0.6
In)
(2)
with t4 = instantaneous, the maximum tolerance is 50 ms
(3)
Tolerance values valid with Trip unit at steady state or on with auxiliary power supply, trip time ≥
100 ms, temperature and signals within operating limits; the tolerances in the table after the notes
are applicable if the conditions are not guaranteed
(4)
the trip unit considers 3% hysteresis for quitting alarm condition
(5)
tolerance valid for frequencies within range: fn ± 2 %. A ± 5% tolerance is applicable for off range
frequencies
