Description
The MCBs of the S 200/S 200 M series have a cur-
rent-limiting effect. They have two different trip releases
acting on the contact mechanism
1. the delayed thermal release providing overload
2. the electromagnetic instantaneous release with
They offer:
Task
To protect against excessive temperature rises of
electric items in the case of overcurrents caused by
overload, short circuit of earth-fault current if assi-
gned according to DIN VDE 0100 Part 430. Protec-
tion against electric shock in the case of excessive
touch voltage caused by insulation fault if assigned
according to DIN VDE 0100 Part 410.
Trip charcteristics and rated current
Independent of the type of characteristic, national codes of practice provide what highest rated current
and/or performance characteristic can be assigned to the conductor cross section to be protected (e.g.
DIN VDE 0100 Part 430).

B-, C- and D-type trip characteristics for line protection
Tripping behaviour according to DIN VDE 0641 Part 11.
Rated current 6 ... 63 A, (C 0,5 ... 63 A). The introduction of these trip characteristics enables direct
assignments of MCBs to the permissible load of lines I z according to DIN VDE 0298 Part 4/11.98, as the
second condition is already fulfilled (I
K-type trip characteristics
Tripping behaviour according to DIN VDE 0660 Part 101 and IEC 947-2, rated current 0.5 ... 63 A,
for circuits where current-consuming appartus cause functional current peaks and for the overcurrent
protection of lines.
Z-type trip characteristics
Tripping behaviour according to DIN VDE 0660 Part 101 and IEC 947-2
Rated current 0.5 ... 63 A in 17 grades. For the protection of semiconductors and measuring circuits with
transformers.
