(1)
not available with Trip unit model Ekip G Touch
(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

; Zone selectivity available with curve t=k; Block configuration available via Ekip Connect
(7)
the protections do not handle the TRIP, just signaling
