ZGXM-MZ2J-24c Signal SPD
General
The ZGXM-MZ2J-24c signal SPD is used for protecting industrial control networks, RS485/422 interfaces,
private wires, automatic control and instrument lines, data lines and telephone devices, fax machines and
other devices from lightning.
It 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 releases
lightning and surge current to ground, and clamps lightning and surge overvoltage to the scope allowed by the
device.
Features
1. Hot-pluggable and compact size.
2. High discharge capacity, fast response (in nano seconds), and low protection level
3. Easy installation: Terminal connection and DIN rail installation
