Short Circuit Selectivity PFL7-../1N/ towards D01-D03 fuse link
In case of short circuit, there is selectivity between the combined RCD/MCB devices PFL7../1N/ and the upstream fuses up to the specified values of the selec-
tivity limit current I
s
[kA] (i. e. in case of short-circuit currents I
ks
under I
s
, only the MCB will trip, in case of short circuit currents above this value both protec-
tive devices will respond).
