Features Flame Resistant PC The housing of this surge arrester is made of flame resistant PC material, which makes it safer to use. The modular design makes it very easy to operate and maintain, with excellent electrical conductivity. Stable Performance: This lightning arrester device uses precision electronic components for longer life and more stable performance, helping you do your job more efficiently. Short Circuit Technology: This lightning arrester device incorporates short circuit technology for overcurrent, overheating and temperature control. It has a maximum continuous operating voltage of 1000V. 2P Rail Mounting: The surge arrester is very easy to install with 2P rail mounting. Standard 35mm rail mounting, used in conjunction with distribution box circuit breakers. QUICK OPENING - When the system experiences a surge due to lightning or other reasons, the lightning arrester will immediately turn on quickly within a few nanoseconds and introduces the surge into the earth to protect the electrical equipment.
