Abstract (en)
[origin: EP0309383A1] It is intended to reduce the outlay required for the production of coils for electromagnetic trip devices. The coil (30) of an electromagnetic trip device (8) consists of a flexible, multi-wire conductor (cable 41), which, because of its flexibility, can be processed manually or by means of a manipulator. There is hence no requirement for the use of winding machines. In addition, components (10, 12) carrying the current path of a switching device (1) onwards can be connected to the ends of a coil conductor even before the coil (30) is wound. A sleeve body absorbs electrodynamic forces which result from short-circuit currents and stress the coil electrodynamically. Low-voltage switching device of compact construction (MCCB). <IMAGE>
