Features PRODUCT PARAMETER: The surge protective device is a 3P design with IP20 protection level and the maximum continuous working voltage is 385V AC. POWER PROTECTION: Efficiently protect the AC power system from thunder or overvoltage, and prevent damage to electrical appliances during thunderstorms. SAFE OPERATION: The surge protector adopts a fireproof shell, which is safe and flame retardant, uses accurate chips, has strong electrical conductivity. EASY INSTALLATION: The protective device adopts modular design, which is easy to use and maintain, the 36MM rail installation ensures a stable structure. WORKING PRINCIPLE: When surge overvoltage occurs in the power supply system, the protector opens quickly and introduces the surge overvoltage to the ground.
