Let-through energy PL4, characteristic B, 1-pole Let-through energy PL4, characteristic C, 1-pole
Short Circuit Selectivity PL4 towards DII-DIV fuse link
In case of short circuit, there is selectivity between the miniature circuit breakers PL4 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
