Abstract

L'invention concerne un appareillage de commutation comprenant au moins une voie de courant principale et au moins une interface de contact qui sont reliées entre elles par le biais d'au moins une liaison électriquement conductrice interne. Pour permettre une surveillance d'un dispositif de protection branché avant l'appareillage de commutation avec un effort de câblage minimum, il est prévu selon l'invention un appareillage de commutation comprenant au moins une voie de courant principale, au moins une interface de contact, laquelle est prévue pour établir le contact avec une unité d'évaluation destinée à déterminer l'état d'un dispositif de protection branché en amont et qui est logée dans un boîtier de l'appareillage de commutation, et comprenant au moins une liaison électriquement conductrice interne entre la ou les interfaces de contact et la voie de courant principale correspondante. L'évaluation directe de l'état de commutation de l'organe de protection sur l'appareillage de commutation permet de supprimer le câblage actuellement nécessaire vers un commutateur auxiliaire supplémentaire sur l'appareillage de protection. Selon l'invention, la réduction de l'effort de câblage permet également de réduire une source d'erreur potentielle.
