Title
(EN) CONFIGURABLE MODULAR HAZARDOUS LOCATION COMPLIANT CIRCUIT PROTECTION DEVICES, SYSTEMS AND METHODS
(FR) DISPOSITIFS, SYSTÈMES ET PROCÉDÉS MODULAIRES ET CONFIGURABLES DE PROTECTION DE CIRCUIT CONFORMES À UN EMPLACEMENT DANGEREUX
Abstract
(EN)
Modular circuit protection devices and configurable panelboard systems include arc-free operation, thermal management features providing safe operation in hazardous environments at lower cost and without requiring conventional explosion-proof enclosures and without entailing series connected separately provided packages such as circuit breaker devices and starter motor contactors and controls.
(FR)
La présente invention concerne des dispositifs de protection de circuit modulaires et des systèmes de dispositif de protection contre les surintensités configurables qui comprennent un fonctionnement sans arc, des caractéristiques de gestion thermique fournissant un fonctionnement sécurisé dans des environnements dangereux à moindre coût et sans nécessiter d'enceintes antidéflagrantes classiques et sans impliquer de boîtiers fournis séparément et connectés en série tels que des dispositifs disjoncteur et des commandes et contacteurs de moteur de démarrage.
