The invention relates to a yoke (1) for a magnetic system of a short circuit triggering device (16), especially for mounting in a circuit-breaker. Said short circuit triggering device (16) comprises a fixed contact carrier (2), a coil (4) with a core (5), an armature (9) which can be moved in the coil (4), and the yoke (1) carrying the core (5). In the event of a short circuit, the armature (9) is impacted by the magnetic forces produced in the coil (4) by the short circuit current, against a switching device (22) which causes the interruption of the current, the fixed contact carrier (2) being embodied as a single element with the yoke (1). |
