Description

technical field

[0001] The invention relates to a tripping relay having a magnetic circuit formed by a yoke and an armature as deflection armature, wherein the yoke has two pole core legs, namely a coil pole core leg and a support pole core The deflection armature can be deflected around a rotation axis arranged between the deflection armature and the support pole core leg, so that the deflection armature and the support pole core leg respectively become the iron core in the magnetic circuit close to the center of rotation. Background technique

[0002] Such a tripping relay, such as that disclosed in "Journal of Electrical Technology" (etz) Vol. In a fault current (FI) protective switch or a differential current (DI) protective switch. In this case, such an FI and DI circuit breaker has, in a similar manner, a main current transformer, through the transformer core of which all current conductors of a line network pass. In the event of a fault current (Fehlerstrom), a trip...
