LAN SPD to protect servers and computer network devices from lightning surge which enters the Ethernet. Our original high-voltage-withstand insulation transformers insulate between the primary side and second side inside the SPD electrically and shutdown lightning surge. It’s easy to install without grounding.

Cat6/10GBase-T applicable

RoHS compliant

No grounding required(Insulation type)


A mounting panel for LAN SPD to install it on a rack is available (optional).
Fixing metal fittings for LAN SPD to install inside a box as a single unit is available (optional).
