Selectivity for miniature circuit breakers/fuses

In the event of a short-circuit, there is selectivity between the

5

SY4, 5SY7, 5SP4 miniature circuit breakers and melting fuses

according to DIN VDE 0636-21 up to the specified values in kA.

Limit values of selectivity for miniature circuit breakers/fuses in kA
