Title (EN) CIRCUIT BREAKER WARNING RELAY AND CONTROL ACCESSORY
(FR) RELAIS AVERTISSEUR ET DE COMMANDE POUR DISJONCTEUR
Abstract:
(EN) A circuit breaker warning and control relay provides visual indication of an impending overcurrent condition. Sufficient time is thereby allotted for manual intervention to prevent damage to material and equipment utilized within sensitive manufacturing processes. The relay can be arranged to automatically shut-down selected equipment in a predetermined order for load-shedding implementation.
(FR) Relais avertisseur et de commande pour disjoncteur, affichant visuellement tout risque imminent de surintensité, ce qui laisse assez de temps pour qu'une intervention manuelle empêche tout dégât au matériel et à l'équipement utilisés au cours de procédés de fabrication délicats. Ce relais peut être installé de manière à arrêter d'urgence automatiquement dans un ordre prédéterminé certains équipements sélectionnés pour le délestage.
