For an EV-link charging station to be protected by, a Compact Residual Current Circuit Breaker with overcurrent protection (RCBO), how can I check the cascading with a ComPacT NSX250F?
Type A residual current protection is absolutely the minimum according to the standard, but more important is whether the charging stations are equipped with the DC leakage sensor. If yes, you can use type A or better type Asi.
If the charging station does not have a DC leakage sensor, you should use type B.
To answer your question, cascading or filiation can be applied between the downstream iC60 RCBO with reference A9D67432, and the upstream NSX250F circuit breaker. See tables in the supplementary technical information at the link below: on page 171 or A-165
