General data
Limiter function with standard devices for 500 V AC and
690 V AC acc. to IEC 60947-2
The table shows the rated ultimate short-circuit breaking capa-
city I
cu
and the rated service short-circuit breaking capacity I
cs
with an upstream standard motor starter protector that fulfills the
limiter function at 500 V AC and 690 V AC. The short-circuit brea-
king capacity can be increased significantly with an upstream
standard motor starter protector.
The motor starter protector which is connected downstream
must be set to the rated current of the load.
With motor starter protector combination assemblies, note the
clearance to grounded parts and between the motor starter pro-
tectors. Short-circuit resistant wiring between the motor starter
protectors must be ensured. The motor starter protectors can be
mounted side by side in a modular arrangement.
