  • High current data transmission
  • Common mode and differential mode protection
  • Data lines, including those isolated from Earth
  • Compact DIN rail enclosure, high density protection
  • Protection of shield wire
  • Location and test categories: D1, C2, C3
  • IEC 61643-21 compliance
DLA 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. D3 types aim to realize fine protection and D2 types is specific for floating application. These products are 1-pair surge protectors with removable module for easy maintenance.
