ZGXL-MDZ4J-24c Signal SPD

General                                                                                
The ZGXL-MDZ4J-24c signal SPD is used for protecting industrial control networks, RS422/485 interfaces, private wires, automatic control and instrument lines, data lines and telephone devices, fax machines and other devices from lightning. This product uses two-stage protection to protect devices, that is, current release in the first stage and current clamping in the second stage. When a transmission line suffers lightning induction or surge attack, the SPD diverts lightning and surge current to ground, and clamps lightning and surge overvoltage to the scope allowed by the device.

Features                                                                                 
Easy installation: Terminal-based connection and guide rail-based installation, Hot-pluggable, compact size, high discharge capacity, fast response (ns), low protection level.
