Features PRODUCT USAGE: Surge voltage protective device is mainly used to protect AC power systems from thunder or overvoltage, suitable for home appliances. SAFE MATERIALS: PC flame retardant shell prevents protector from burning out internal component, and precise chip ensures strong electrical conductivity. IP20 PROTECTION: The 4P surge arrester device has IP20 protection grade, with stable performance and good conductivity, and protects electrical equipment. WORKING PRINCIPLE: When a surge overvoltage occurs in the system due to thunder, the protector opens quickly and introduces the surge overvoltage into the ground. RAIL INSTALLATION: The overvoltage protector adopts modular design, with 36MM rail installation, easy to use and maintain, and convenient to install.
