Class D Yellow Surge Protector 380V Surge Protective Device EL1-D-20 Application scope
Power industry: The power system is the main victim of lightning disasters. Lightning strikes can cause serious consequences such as overheating, short circuit, and explosion of power equipment, affecting the stability and safety of power supply. Therefore, the power industry needs to install surge protectors in key locations such as substations, distribution rooms, transmission and distribution lines, generators, etc. to prevent lightning from causing damage to the power system. Class I and II switch-type surge protectors are usually used to withstand the impact of large currents.
Communications industry: Communications equipment and network systems are very sensitive to surge voltages. Once struck by lightning or other interference, it may cause data loss, communication interruption, or equipment damage. Therefore, the communications industry needs to install surge protectors at all levels, including base stations, switches, routers, servers, terminal equipment, etc. Combined surge protectors of Class I, II and III are usually used to achieve hierarchical protection.
Construction industry: Buildings are important objects of lightning protection. Various electronic equipment inside the building need to be protected from the effects of lightning strikes and surges. Therefore, the construction industry needs to install surge protectors at different levels such as main distribution boxes, distribution boxes, and terminal equipment to achieve partitioned protection. Generally, voltage-limiting surge protectors of Class I, II and III are used to reduce the level of protection.
