Selectivity for miniature circuit breakers/circuit breakers
In the event of a short-circuit, there is selectivity between miniature
circuit breakers and motor starter protectors according to
IEC/EN 60947-2 or DIN VDE 0660-101 up to the specified values
in kA.
Limit values of selectivity for miniature circuit breakers/fuses in kA
1) In 240/415 V, 50 Hz systems, the selectivity limits are reduced by 10 %.
