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