Abstract
Un coupe-circuit (1) en cas de défaut à la terre continuant à assurer une protection de défaut à la terre dans l'éventualité d'une perte de neutre comprend un dispositif de blocage composé d'une paire de diodes Zener en opposition (D7, D8) complétant un chemin d'alimentation d'un coupe-circuit lors d'une perte de neutre. Le coupe-circuit (1) comprend également un circuit redresseur de réserve composé d'une paire de diodes (D5, D6) complétant un redresseur pleine onde comportant des entrées de ligne (2) et de terre (4) dans l'éventualité d'une perte de neutre (3).
