ZGXM-MZ2J-24c Signal SPD
General
The ZGXM-MZ2J-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.
