This table shows the rated ultimate short-circuit breaking
capacity I
cu
and the rated service short-circuit breaking
capacity I
cs
of the 3RV1 motor starter protectors with different
inception voltages dependent of the rated current I
n
of the motor
starter protectors.
Motor starter protector infeed is permissible at the upper or
lower terminals without restricting the rated data. If the short-cir-
cuit current at the place of installation exceeds the rated short-
circuit breaking capacity of the motor starter protector as speci-
fied in the table, a back-up fuse is required. Alternatively, a
motor starter protector with a limiter function can be connected
upstream.
The maximum rated current for the back-up fuse is specified in
the tables. The rated ultimate short-circuit breaking capacity
then applies as specified on the fuse.
Fuseless construction
Motor starter protector contactor combinations for short-circuit
currents up to 50 kA can be ordered in the form of fuseless load
feeders according to Chapter 6.
1) 10 % overvoltage.
2) 5 % overvoltage.
3) Back-up fuse only required if the short-circuit current at the place of
installation > I
cu
.
4) Alternatively, fuseless limiter combinations for 690 V AC can also be used.
5) The values for the 3RV17 42 circuit breakers have been tested only up to
400 V/415 V AC; values > 440 V AC on request.
