Patent

CA 2387191

The invention concerns a reverse current relay comprising a relay magnet and a protective device each capable of acting through a multipolar member on mobile contacts in response respectively to a deliberate command or an electric fault detection. A control mechanism (40) for the contacts is provided with a electromagnetic tripping element (41). The protective device (30), preferably interchangeable, is connected to the relay magnet (20) by a control linkage (33B) and to the control mechanism (40) by a triggering linkage (33A), so as to deliver, in the event of a fault, a triggering signal on the triggering linkage. The relay magnet (20) is powered with direct current and the protective device (30) adjusts its voltage supply.

Contacteur-disjoncteur comprenant un électroaimant de commande et un dispositif de protection aptes à agir chacun par un organe multipolaire sur des contacts mobiles en réponse respectivement à une commande volontaire et à la détection d'un défaut électrique. A un mécanisme de commande (40) des contacts est adjoint un déclencheur électromagnétique (41). Le dispositif de protection (30), de préférence interchangeable, est relié à l'électroaimant (20) par une liaison de commande (33B) et au mécanisme de commande (40) par une liaison de déclenchement (33A), de manière à délivrer une énergie électrique d'alimentation à l'électroaimant sur la liaison de commande et, en cas de défaut, un signal de déclenchement sur la liaison de déclenchement. L'électroaimant (20) est du type à courant continu et le dispositif de protection (30) adapte sa tension d'alimentation.
