The invention relates to a disconnecting apparatus (1) for direct current interruption between a direct current source (2) and an electrical device (3), in particular between a photovoltaic generator and an inverter, with a current-conducting mechanical switching contact (7a, 7b) and with semiconductor electronics (8) connected in parallel with the switching contact (7a, 7b). The semiconductor electronics (8) are non-conducting when the switching contact (7a, 7b) is closed, wherein a control input (15) of the semiconductor electronics (8) is wired with the switching contact (7a, 7b) in such a way that, when the switching contact (7a, 7b) opens, an arc voltage (U LB) generated as a result of an arc (LB) via the switching contact (7a, 7b) switches the semiconductor electronics (8) to be conducting.

L'invention concerne un disjoncteur (1) pour l'interruption de courant continu entre une source de courant continu (2) et un dispositif électrique (3), notamment entre un générateur photovoltaïque et un onduleur, comprenant un contact de commutation (7a, 7b) mécanique conduisant le courant et une électronique à semi-conducteurs (8) connectée en parallèle au contact de commutation (7a, 7b). L'électronique à semi-conducteurs (8) bloque le courant quand le contact de commutation (7a, 7b) est fermé, une entrée de commande (15) de l'électronique à semi-conducteurs (8) étant connectée au contact de commutation (7a, 7b) de telle manière que, quand le contact de commutation (7a, 7b) s'ouvre, une tension d'arc (ULB) générée par l'intermédiaire du contact de commutation (7a, 7b) à la suite d'un arc électrique (LB) enclenche de manière conductrice l'électronique à semi-conducteurs (8).
