Details
The SPD-ETH-1 is a rugged, industrial-grade, 8-wire, passive 10/100/1000M Ethernet surge protector designed to safeguard sensitive network equipment from voltage surges and spikes on data lines. It employs a robust 3-stage surge protection circuit – utilizing Gas Discharge Tubes (GDT), protection resistors, and Transient Voltage Suppressors (TVS) - for maximum protection. Connected in series at the equipment input, the protector activates during a surge or remote lightning: the GDT ionizes to divert high-voltage energy to earth ground, while the TVS clamps any residual voltage to a safe level. This passive design requires no external power and supports data rates up to 1000Mbps, making it compatible with non-PoE, PoE, and PoE+ devices. The SPD-ETH-1 comes with a dedicated cable lug for solid earth ground connections and can be mounted directly onto a standard 35mm DIN rail, making it an ideal solution for heavy-duty industrial applications.
