8 - Hi-Touch protections

Availability (Performance)

The following is a complete list of the protections (and related parameters) available with all the Ekip Hi-Touch and Ekip G Hi-Touch trip units, in
the Protections and Advanced menus:
Name Protection against
S2 Selective short-circuit
(3)
D Directional short circuit
(6)
UV2 Minimum voltage
OV2 Maximum voltage
UF2 Minimum frequency
(5)
OF2 Maximum frequency
(5)
Double configuration of the
Set A-B
protections
(1)
Detailed description in the Design Engineer's manual.
(2)
Locking Function available via Ekip Connect.
(3)
For all the UL versions the maximum time allowed by the trip unit is 0.4 seconds. If a higher value is set, the trip unit signals the error and forces
the parameter to 0.4 seconds.
(4)
Directional Zone Selectivity works as an alternative to S and G Zone Selectivity.
(5)
Protection not active for voltages <30V.
(6)
The protection does not detect the direction of fault current for voltages < 5V.
