The power surge protector is divided into three levels: level one (level B), level two (level C), and level three (level D). According to the IEC (International Electrotechnical Commission) standard of the divisional lightning protection and multi-level protection theory, Class B lightning protection belongs to the first-level lightning protection device, which can be applied to the main power distribution cabinet in the building; Class C belongs to the second-level protection Lightning devices are used in the branch distribution cabinets of buildings; Class D is a third-level lightning protection device, which is used in the front end of important equipment to provide fine protection to the equipment.
