RS-485 communications networks are widely used in industrial installations due to their lengths which can reach up to 1000m, this makes them highly vulnerable to inductions. This range of surge arresters protect networks balanced in 1 or 2 pair configurations (3 wires for 485). It is designed for installation on DIN rail and for screw connection.
