Applications: 
 Class D series power mine used in LPZ1 or LPZ2 to the LPZ3 area at the junction, are fine lightning protection of power lines and anti-surge protection. Usually installed in front of the electrical equipment, such as household distribution box, the computer center equipment, control room equipment, information equipment and other electronic equipment and control equipment, power line front end, as the power lines of the third level of lightning protection anti-wave protection. 
 Features: 
 Line with national GB18802.1-2002/IEC61643-1: 1998 standard and YD/T1235.2-2002 product design and testing standards. SPD connected in series in the circuit, further reducing the line impedance and inductance; built-in thermal protection device stream invalid, protection due to overheating, over current, breakdown failure, automatically from the grid out of; flow automatic overload protection device set too when the protection due to the over-current, breakdown failure can automatically detachment from the grid; SPD needs to be grounded, the ground should be consistent with the lightning protection specification requirements (ground resistance recommended not greater than 10Ω), and The ground wire as far as possible short and straight.
