General data
Short-circuit breaking capacity I
cuIT
in the IT system
(IT network) according to IEC 60947-2
3RV1 motor starter protectors are suitable for operation in
IT systems. Values valid for triple-pole short-circuit are I
cu
up to
I
cs
. In case of double ground fault on different phases at the in-
put and output side of a motor starter protector, the special
short-circuit breaking capacity I
cuIT
applies. The specifications
in the table below apply to 3RV1 motor starter protectors.
In the colored areas, I
cuIT
is 100 kA, or in some ranges it is 50 kA.
Therefore the motor starter protectors are short-circuit resistant
in these ranges.
If the short-circuit current at the place of installation exceeds the
rated short-circuit breaking capacity of the motor starter protec-
tor as specified in the table, a back-up fuse is required. The ma-
ximum rated current for the back-up fuse is specified in the ta-
bles. The rated short-circuit breaking capacity then applies as
specified on the fuse.
