CITEL MJ6-1T/D – RJ11 Surge Protector for Single Telephone/Data Line

Type 2 SPD | RJ11 Interface | Hybrid GDT + TVS Technology | Wall-Mountable

The CITEL MJ6-1T/D is a compact, high-performance Type 2 surge protection device (SPD) designed to safeguard single-pair telephone and data lines from transient overvoltages caused by lightning strikes and switching events. Engineered for RJ11 interfaces, this SPD is ideal for protecting equipment connected to PSTN, ADSL2, or VDSL lines.

Utilising a hybrid protection approach that combines Gas Discharge Tube (GDT) and Transient Voltage Suppression (TVS) diode technologies, the MJ6-1T/D offers both common-mode and differential-mode protection. Its aluminium housing and wall-mountable design ensure durability and ease of installation in various environments.
