13.2.9.12 Summary table of the protection function settings for the PR122/P
(1)
The minimum value of this trip is 1s regardless of the type of curve set (self-
protection).
(2)
These tolerances are based on the following assumptions:
- self-supplied relay at full power (without start-up)
- presence of auxiliary power supply
- two-phase or three-phase power supply
- preset trip time ≥ 100 ms.
(3) no-trip time
(4) the protection G is disabled for current values greater than 4In, where I4 < 0.5 In,
greater than 6 In, where 0.5 In
≤
I4 < 0.8 In and greater than 8 In where I4
≥
0.8 In.

Max trip time
For all cases not covered by the above hypotheses, the following tolerance values
