Warning Iw
(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:
- relay at full power (without start-up)
- preset trip time ≥ 100 ms
no-trip time
(3)
the protection G is disabled for current values greater than 4In, where I4 < 0.5 In,
(4)
greater than 6 In, where 0.5 In ≤ I4 < 0.8 In and greater than 8 In where I4≥ 0.8 In.
