In case of short circuit, there is selectivity between the miniature circuit breakers PL6 and the upstream fuses up to the specified values of the selectivity 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 protective devices
will respond).
*) basically in accordance with EN 60898-1 D.5.2.b
1)
Selectivity limit current I
s
under 0.5 kA
2)
Selectivity limit current I
s
= rated breaking capacity I
cn
of the MCB
no selectivity
