Patent

CA 2312486

The invention relates to an electromagnetic relay, comprising a magnetic system (6) with an exciting field coil (WR), a core and an armature. Each load current circuit can be closed by a movable contact element and by at least one fixed contact element. A reed contact (KR) is coupled to a load current conductor (1) in each load current circuit. Means to generate and process an overcurrent signal and to disconnect the control current are coupled to the reed contact (KR).

L'invention concerne un relais électromagnétique comportant un système magnétique (6) qui présente une bobine d'excitation (W¿R?), un noyau et un induit. Dans ce relais, chaque circuit de courant de charge peut être fermé par un élément de contact mobile ainsi que par au moins un élément de contact fixe. Un contact à lame vibrante (K¿R?), associé à chaque circuit de courant de charge, est couplé à un conducteur de courant de charge (1). Des moyens servant à produire et traiter un signal d'intensité excessive et servant à couper le courant de commande sont couplés au contact à lame vibrante (K¿R?).
