| Option 1 | S3D2 option : insulating bracket with built-in ground lead disconnector. In case of failure, type S3D2 disconnecting device separates automatically the arrester bottom terminal from earth. It ensures continuity of service and it also provides a local visual indication of the disconnected status. Sensitivity 5 A |
| Option 2 | Option S3D2 : support isolant avec module intégré de déconnexion. En cas de défaillance, le système de déconnexion type S3D2 sépare automatiquement la borne inférieure du parafoudre de la terre. Il assure la continuité de service et fournit aussi une indication visuelle locale de l'état déconnecté. Sensibilité 5 A |
