Abstract
(EN)
Compliant electrical circuit protection devices are described for use in hazardous environments without presenting ignition risks for potentially explosive environmental conditions. Sensing features and systems may evaluate wiring limits and user selected settings for compatibility, detect loose connections and operating parameters to ensure safe operation of the device, and to intelligently diagnose and manage issues of concern for the circuit protection devices as well as the larger electrical power system.
(FR)
L'invention concerne des dispositifs de protection de circuit électrique conformes destinés à être utilisés dans des environnements dangereux sans présenter de risques d'ignition dans des conditions environnementales potentiellement explosives. La détection de caractéristiques et des systèmes peuvent évaluer des limites de câblage et des réglages sélectionnés par l'utilisateur pour une compatibilité, détectent des connexions lâches et des paramètres de fonctionnement pour assurer un fonctionnement sûr du dispositif, et pour diagnostiquer et gérer de manière intelligente des problèmes de préoccupations des dispositifs de protection de circuits ainsi qu'un système d'alimentation électrique plus grand.
