Abstract

Un dispositif disjoncteur de fuite à la terre à trois phases est décrit. Le dispositif disjoncteur de fuite à la terre à trois phases peut comprendre des contacteurs, un module de commande de contacteur conçu pour faire en sorte que les contacteurs se ferment pendant lexploitation normale du dispositif disjoncteur de fuite à la terre et souvrent sur la base de la réception dun signal de dérangement, un module de détection de courant, un module de suppression transitoire, un module de détection derreur de câblage, un module dessai de fuite à la terre, un module de détection de charge au sol et un module de sécurité. Dans certains exemples, le dispositif disjoncteur de fuite à la terre peut comprendre les modules déclarés conformément à la norme UL 943C.
