Surge voltage and surge current protection for communication and data transmission lines. Protection connector (1DA) with surge current protection via PTC thermistors, for analogue, ISDN and ADSL lines. Integrated coarse and fine protection and fail-safe contact. Earthing by a grounding bar, which is connected to the backmount frame via the disconnection module.
