Title
(EN) BELL ALARM AND LOCK-OUT FOR HIGH AMPERE-RATED CIRCUIT BREAKERS
(FR) ALARME SONORE ET DISPOSITIF DE VERROUILLAGE POUR COUPE-CIRCUIT DE FORTE INTENSITE
Abstract
(EN) A combined bell alarm and lock-out accessory (20) is connected with the electronic trip unit (60) that controls a high ampere rated circuit breaker (10). The accessory (20) interacts with the circuit breaker operating mechanism (9) to activate the bell alarm upon circuit interruption and to prevent the closing of the circuit breaker contacts until the accessory (20) is manually reset.
(FR) Un accessoire (20) combinant une alarme sonore et un dispositif de verrouillage est raccordé au dispositif de déclenchement électronique (60) commandant un coupe-circuit de forte intensité (10). L'accessoire (20) agit en combinaison avec le mécanisme (9) d'actionnement du coupe-circuit pour activer l'alarme sonore en cas d'interruption du circuit et pour empêcher la fermeture des contacts du coupe-circuit tant que l'accessoire (20) n'est pas remis manuellement à l'état initial.
