B+B SmartWorx BB-485HESP ULI-246T - RS-485 (2W) (Terminal Block) High Energy Surge Protector

These three-stage surge suppressors protect against lightning strikes and other voltage disturbances with three stages of protection for each line: a gas discharge tube followed by a series resistor and finally a Transient Voltage Suppresser (TVS). The devices are housed in rugged cases with a protected signal ground connection and dedicated chassis ground lugs. In order to work properly, it is important to have a good connection between the #10 screws and a solid earth ground.
