Further details about the protections are given in document 1SDH001330R1002.
(1)
protection cannot be deactivated; its trip parameters are set by ABB and cannot be edited
(2)
not available with LSI version of Trip unit
(3)
can be activated with protection MCR = Disable
(4)
can be activated with protection I = Disable
(5)
if the presence of sensor S.G.R. is activated, the submenu of protection G will be replaced by that of protection Gext, in the Advanced
menu; with Trip unit models Ekip Hi-Touch and Ekip G Hi-Touch, the two protections are available at the same time
(6)
Thermal memory available with curve t=k/I
2
; Zone selectivity available with curve t=k; Block configuration available via Ekip Connect
(7)
the protections do not handle the TRIP, just signaling
