Abandoning time for ARC SHOT2 ([TRR_MS2]): 0.4s
The setting of [TRR_MS2] should be longer in duration than the [TD_MS2] timer setting. In
this case, it should be set > 0.33s. Setting chosen is 0.4s.
Note: The ARC coordination function may be enabled if there is another downstream CB
with which shot coordination is required. The function is enabled by setting 'On'
for scheme switches [ARCCO-OCEN] and [ARCCO-EFEN]. The default settings for
overcurrent pickup (CO-OC=1.0/5.0 A) and earth fault pickup (CO-EF=0.30/1.5 A)
should be adequate for most applications.
