Abstract
(EN)
Hazardous location compliant solid state circuit protection devices include safety lockout components ensuring disconnection as a safeguard in the completion of power system maintenance and service tasks by responsible personnel. The safety lockout components may include a mechanical lockout interfacing with a physical lock element, an electrical lockout implemented through the controls of the solid state circuit breaker device, and combinations thereof. Visual device feedback and confirmation may be provided to personnel that the lockouts have been successfully activated, as well as successfully deactivated to reconnect and restore operation of the load side circuitry.
(FR)
La présente invention concerne des dispositifs de protection de circuit à semi-conducteur conformes à un emplacement dangereux qui comprennent des composants de verrouillage de sécurité qui garantissent la déconnexion en tant que protection dans l'achèvement de tâches de maintenance et d'entretien de système d'alimentation par un personnel responsable. Les composants de verrouillage de sécurité peuvent comprendre un verrouillage mécanique qui effectue une interface avec un élément de verrouillage physique, un verrouillage électrique mis en œuvre par l'intermédiaire des commandes du dispositif disjoncteur à semi-conducteur, et des associations de ceux-ci. Une rétroaction et une confirmation de dispositif visuel peuvent être fournies au personnel pour indiquer que les verrouillages ont été activés avec succès, ainsi que désactivés avec succès pour reconnecter et restaurer le fonctionnement des circuits côté charge.
