Abstract (en)
[origin: EP1237171A2] The arrangement has an electromagnetic short circuit trigger (4) per main currant path with a spring loaded hinged armature (11) in contact with a setting element (4) for all main current paths when at rest and attracted by a magnet yoke (12) carrying current in the short circuit case. A contact element (14) for outputting the blocking signal arranged between the armature and the yoke is changed from open to closed by the attracting armature. The arrangement has an actuating mechanism with a latching device, whereby a switch subject to a short circuit delivers a blocking signal to the actuating mechanism or triggering system of the preceding switch. An electromagnetic short circuit trigger (4) is provided for each main currant path with its spring loaded hinged armature (11) in contact with a setting element (4) for all main current paths when at rest and attracted by a magnet yoke (12) carrying current in the short circuit case. A contact element (14) for outputting the blocking signal arranged between the armature and the yoke is changed from open to closed by the attracting armature.
