arrester for AC power (Socket Strip with Lightning Protection) before you plug AC power cord into the
switch, thus to prevent the possible damage to the switch due to lightning strike. You can use cable clips
and screws to fasten the lightning arrester for AC power on the cabinet, workbench or the wall of
equipment room.
