Load Capacity PKN6-../1N/
Effect of ambient temperature (MCB component)
Short Circuit Selectivity PKN6-../1N/ towards DII-DIV fuse link
In case of short circuit, there is selectivity between the combined RCD/MCB devices PKN6../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).
*) basically in accordance with EN 60898-1 D.5.2.b
