Installation Sheet
DLC compact 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 or on modular panel and are available for most of the transmission lines These products are 1-pair surge protectors with monobloc enclosure
