(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:
- energized protection release in service conditions (without start-up) with
2 or 3 phases energized and/or in the presence of auxiliary supply.
- Preset trip time
≥
100 ms.
-
Temperatura e correnti entro i limiti di funzionamento.
(3)
The interval of time for which the protection is activated can be selected
via Ekip Connect, and is calculated from the moment the CB closes.
(4)
Protection G can be automatically disabled by the release on the basis of
the current measured. Per le casistiche 1.6.8.
(5)
Max trip time.
(6)
La soglia minima delle protezioni G e Gext, in assenza di Vaux diventa
0,2In.
