2.7.3 Short-circuit breaking capacity I
cn
in acc. with IEC 60 947-2
The table lists the rated limit short-circuit breaking capacity I
cu
and the rated service short-circuit breaking capacity I
cs
of 3RV1 circuit
breakers with different inception voltages and related to the rated current I
n
of the circuit breakers.
The incoming supply of the circuit breakers is permissible at the upper or lower terminals irrespective of the rating.
If the short-circuit current at the installation location exceeds the rated short-circuit breaking capacity of the circuit breaker specified in
the table, a backup fuse is required. You can also use an upstream circuit breaker with a limiter function.
The maximum rated current of this backup fuse is specified in the tables. The rated short-circuit breaking capacity specified for the
fuse then applies.
Circuit breaker/contactor combinations for short-circuit currents of up to 50 kA can be used as fuseless load feeders in acc. with Part 5.
