PHL-T-RJ11 Network SPD（Telephone network）

Product overview

Network SPD (Surge Protective Device) is a device used to protect telecommunications systems from electrical interference such as sudden voltages, surges, and lightning strikes. They are usually installed at the input end of telecommunications lines to prevent overvoltage damage to sensitive equipment or systems.

The telecommunications system includes telephone lines, data lines, network lines, etc., which often face threats from natural disasters such as lightning, and therefore require appropriate protective measures. The function of network SPD is to guide the sudden voltage introduced in the telecommunications system to the ground when it reaches a dangerous level, in order to protect the equipment from damage.

When installing network SPD, it is important to choose products that are suitable for the characteristics of the telecommunications line and follow the manufacturer's instructions for proper installation. This can ensure that the telecommunications system can effectively protect equipment in sudden events such as lightning, ensuring the stability and reliability of communication.
