Applications: 
 Network communications room for power lines, monitoring, control room, the fire control room, microwave transmission stations, residential quarters, enterprises and institutions from LPZ0 enter LPZ1 district or from LPZ1 enter LPZ2 District power lines installed in low voltage distribution systems, as power lines in the first or second lightning anti-surge protection. 
 Features: 
 Line with national GB18802.1-2002/IEC61643-1: 1998 standard and YD/T1235.2-2002 product design and testing standards. Line shunt technology, design flow capacity and power lines parallel connection, the output residual depression. The built-in thermal overcurrent trip protection device, no external fuses to ensure that the SPD malfunctions automatically with the power grid from the phenomenon of spontaneous combustion and electrical short circuit, which does not occur. Built-in SPD deterioration protection indicator; Phase indicator; phase line, the zero-line errors wiring instructions. Distant signal alarm function. The lightning count display.
