A trip circuit supervision circuit is disclosed for use in combination with a trip circuit comprising a circuit breaker trip coil connected in a supply line from a supply voltage and a trip relay contact connected in series with the circuit breaker trip coil. The supervision circuit is connected across the relay trip contact and includes a current sensing device. During normal operation, the supervision circuit draws a constant current from the supply line independent of supply voltage. Thus, changes in the current measured by the current sensing device enable the integrity of the supply voltage to be checked.

La présente invention concerne un circuit de surveillance de circuits de déclenchement, avec un circuit de déclenchement consistant en une bobine de déclenchement de coupe-circuit dans une ligne d'alimentation d'une source de tension, et en un contacteur de relais de déclenchement branché en série avec la bobine de déclenchement du coupe-circuit. Le circuit de surveillance est branché au travers du contacteur de déclenchement de relais et comprend un dispositif de détection du courant électrique. En fonctionnement normal, le circuit de surveillance prélève du courant constant de la ligne d'alimentation, indépendamment de la tension d'alimentation. Ainsi, tout écart de courant mesuré par le dispositif de détection de courant permet de vérifier l'intégrité de la tension d'alimentation.
