breaker closing
Instantaneous short-circuit Zone selectivity, activation function and
2I
programmable mode, Delay ON/OFF
IU Current unbalance Trip enable, Algorithm
Neutral Different protection on neutral phase
T Abnormal temperatures Trip enable
Iinst (1) Instantaneous short-circuit
Harmonic Distorted waveforms
distortion (7)
Hardware Trip Internal connection errors
Current thresholds
(7) Control thresholds exceeded Direction of current flow
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 ; Zone selectivity available with curve t=k; Block configuration available via Ekip Connect
(7) the protections do not handle the TRIP, just signaling
