Abstract

La présente invention concerne un interrupteur différentiel tétrapolaire comprenant un capteur différentiel agencé pour détecter un courant de fuite, un dispositif de commande connecté au capteur et un mécanisme de déclenchement des contacts de l'interrupteur. Le mécanisme de déclenchement comporte un barreau de commutation (16) qui porte des contacts mobiles (15a, 15b, 15c, 15c). Il est en outre équipé de deux renflements (18, 19) qui agissent à la manière de cames sur les contacts mobiles (15a, 15d) de telle manière que l'écart entre ces contacts par rapport aux contacts fixes (14a, 14d) correspondants est inférieur à celui des contacts mobiles (15b, 15c) par rapport à leurs contacts fixes (14b, 14c). De ce fait, les séquences de fermeture autorisées suivantes des contacts en cas de détection de fuite sont respectées: neutre - phase - phase - phase ou phase - neutre - phase - phase.The present invention relates to a four-pole differential switch comprising a differential sensor arranged to detect a leakage current, a control device connected to the sensor and a mechanism for tripping the contacts of the switch. The trigger mechanism comprises a switching bar (16) which carries movable contacts (15a, 15b, 15c, 15c). It is also equipped with two bulges (18, 19) which act like cams on the movable contacts (15a, 15d) so that the distance between these contacts with respect to the corresponding fixed contacts (14a, 14d) is less than that of the movable contacts (15b, 15c) with respect to their fixed contacts (14b, 14c). As a result, the following authorized closing sequences of the contacts in the event of leak detection are observed: neutral - phase - phase - phase or phase - neutral - phase - phase.
