Installation Sheet

DLAH surge protectors are designed to protect, against surge voltages due to lightning, terminals equipment connected to industrial buses, telecom lines or datalines. These surge protectors must be installed on symmetrical DIN rail and are available for most of the transmission lines: line voltage from 6 to 170V, bitrate up to 10 Mbit/s. These products are 1-pair surge protectors with removable module for easy maintenance.
