2 - Standard Protections

List
The Standard protections available for all Ekip Touch models, are:
Name Type of protection
L Overloads with inverse long-time delay
S Short-circuit with adjustable delay
S2 Short-circuit with adjustable delay
I (3) Instantaneous short-circuit
G Earth fault with adjustable delay
(2)(5)
Instantaneous short-circuit on circuit-
MCR
(4)
breaker closing
Instantaneous short-circuit
2I
programmable
IU Current unbalance
Neutral Different protection on neutral phase
T Abnormal temperatures

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
not available with LSI version of Trip unit
(2)
can be activated with protection MCR = Disable
(3)
(4) can be activated with protection I = Disable
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
(5)
menu; with Trip unit models Ekip Hi-Touch and Ekip G Hi-Touch, the two protections are available at the same time
Thermal memory available with curve t=k/I
(6)
the protections do not handle the TRIP, just signaling
