Device Variant
Self-powered device, parameter settings via
DiggiMEC / Smart view
1
Self-powered device, parameter settings via
DIP switches and/or DiggiMEC / Smart view
2
Self-powered device, parameter settings via
HEX switches and/or DiggiMEC / Smart view

CT Type
The WIC1-compatible CTs (WIC1WE1AS1 …
WIC1W6AS1) are used for the phase current
measuring inputs.
S
Special Broad-Range CTs (2 secondary windings)
shall be connected to the phase current
measuring inputs.
B
Ground Current Method
The ground (earth) current is calculated out of the
measured phase currents.
N
The ground (earth) current can be measured at a
dedicated 4th CT input. However, the device can also
be set (via DiggiMEC / Smart view) to operate using
calculated ground (earth) current.
G
Nominal Frequency
The nominal frequency can be set to 50 Hz or 60 Hz (via
DiggiMEC / Smart view).
0
The factory preset for the nominal frequency is 50 Hz, but can
also be set to 60 Hz (via DiggiMEC / Smart view).
5
The factory preset for the nominal frequency is 60 Hz, but can
also be set to 50 Hz (via DiggiMEC / Smart view).
6
Outputs
The Trip Command is assigned to the “TC” (Trip Coil pulse) output.
(This assignment is pre-defined and fixed.)
