Characteristics:
In line with SPD test standards as IEC61643-1 (1998-02), GB18802.1-2002 and GA173-2002, and sustained voltage up to 440V (each way). It is in line with the large fluctuations actual request of national power grid, and has short-circuit over-current release function to prevent a fire, explosion accidents with standard modular design and 35mm standard rail installation. It is simple and convenient.
