Telecommunication and data transmission devices (PBX, Modems, Data terminals..) are becoming increasingly vulnerable to lightning-induced voltages surges. These devices are becoming more complex, sensitive and share a common grounding connection with other networks. So CITEL developed a range of surge protectors for Telecom/Data networks and Industrial networks.

  • DIN Rail Telecom/Data surge protector

    DLA and DLU surge protectors are designed to protect, against surge voltages dues to lightning, terminals equipment connected to industrial buses, telecom lines or datalines.
