2.7.3 Limiter function with standard devices for 500 VAC and 690 VAC in acc. with IEC 60 947-2
The table lists the rated limit short-circuit breaking capacity I
upstream standard circuit breaker that fulfills the limiter function at 500 VAC and 690 VAC.
The short-circuit breaking capacity can be significantly increased using the upstream standard circuit breaker with a limiter function.
The circuit-breaker connected downstream, should be set to the rated current of the load. Be sure when you set up circuit breaker
combinations to note to the distances between the grounded parts and the distances between the circuit breakers.
Make sure that the cabling between the circuit breakers is short circuit-proof. You can set up the circuit breakers side by side.
