The ZGXT-4R-5 Signal SPD is mainly used for protection of the interface circuit of Ethernet with POE, greatly improving the Ethernet’s ability to withstand overvoltage and lightning impulses.

The ZGXM-1B-5 is used to protect signal systems such as cameras, monitors, and mobile communications, and to suppress inductive lightning and other shock waves from the signal line to protect the device from damage.

ZGXH-2R-5 type signal surge protector is mainly used to protect high-speed Ethernet internal interface circuit, featuring high transmission rate (above 100Mbit s).
