Feature: 1. OVERVOLTAGE PROTECTION: The protector will turn on immediately when a surge overvoltage occurs due to lightning strike or other reason, introduce the overvoltage into the ground to protect the electrical equipment. 2. 36MM RAIL INSTALLATION: The surge protector is modular designed with standard 36mm guide rail, easy to install, can used in conjunction with distribution box circuit breakers. 3. FLAME RETARDANT SHELL: Made of safety high strength PC material, the shell is flame retardant, fireproof, more reliable to use. 4. PRECISE ELECTRONIC COMPONENTS: The protector has good conductivity, adopt precise electronic components, helping to complete work more efficiently. 5. MULTI PURPOSE: The surge protector is simple to use and maintain, can be widely used in residential, office building and industrial fields.
