Abstract

Un circuit protecteur pour appareils électriques comprend une ligne de sécurité (4) isolée qui s'étend de l'appareil électrique correspondant (6) au circuit protecteur (2). La ligne de sécurité (4) présente à l'intérieur de l'appareil (6) au moins une zone non isolée qui ne touche pas les parties d'alimentation en courant. Un premier dispositif commutateur (R1) connecté à la ligne de sécurité (4) et à un potentiel de référence, ainsi qu'un deuxième dispositif commutateur (R2) actionné par le premier dispositif commutateur (R1) sont agencés entre la phase (10) et le conducteur neutre (2) de l'alimentation en courant électrique de l'appareil (6) et séparent à l'état activé de commutation l'appareil (6) de la phase (10) et du conducteur neutre (12). Le deuxième dispositif de commutation (R2) est connecté de telle façon avec la phase (10) et le conducteur neutre (12) qu'il reste à l'état activé de commutation après avoir été activé par le premier dispositif de commutation (R1).
