TTC-6P-3-HF-F-M-EX-24DC-UT-I - Parafoudre
Parafoudre basse tension avec indicateur d'état intégré et sectionnement par couteau pour un circuit de signalisation à 3 fils à sécurité intrinsèque, avec potentiel de référence commun. Pour applications HF. Mise à la terre indirecte par éclateur à gaz, compatible HART. Adapté à l'utilisation dans un système de bus de terrain (par ex. PROFIBUS PA) selon le concept FISCO, APL ready. Utilisable dans des circuits sécurisés jusqu'à SIL 3.
- Peu encombrant et économique grâce à une petite largeur de 6 mm seulement
- Surveillance permanente des parafoudres et indicateur d'état mécanique avec signalisation à distance en option
- Une sélection simple qui répond à chaque exigence dans le domaine MCR grâce à un portefeuille complet de caractéristiques produit sur mesure
- Contrôle et documentation simplifiés avec CHECKMASTER 2 grâce à des modules de protection enfichables
- Aucune influence du signal en cas de travaux d'entretien grâce à une insertion et retrait exempts d'impédance des fiches de protection
