Lightning Protection-Surge protective Device-18/20 μ S Power supply surge protector

Introduce

WD1 series surge protector (hereinafter referred to as SPD) is applicable to T, T, TN-C, TN-S, TN-C-S, and other power supply systems with AC 50/60Hz and rated voltage of 380V to protect indirect lightning, direct lightning impact, or other surges with overvoltage during breakdown. Class III surge protector according to IEC61643-1:1998-02 standard. Type D surge protector.
SPD has common mode (MC) and differential mode (MD) protection modes.
SPD conforms to GB18802.1/IEC61643-1.

Install

Installed at the junction of LPZI or LPZ2 area and LPZ3 area, 35mm standard guide rail is used for installation, and the connecting copper multi strand flexible wire is 6~16mm2.
Each pole of WD1 must be protected - using fuses or miniature circuit breakers.
It is applicable to user distribution box, computer equipment and information equipment. In front of or nearest socket box of electronic equipment and control equipment.

Working Principle

SPD is one port, electric shock protection, indoor fixed installation, voltage limiting type.
SPD built-in separator. When SPD fails due to overheating and breakdown, the disconnector can automatically disconnect it from the power grid and give an indication signal. The visual window displays green when the SPD is working normally, and red when the SPD is out of service.
IP+N, 2P+N, 3P+N are composed of 1P, 2P, 3P SPD+NPE zero ground protection modules, which are applied to TN-C-S, TN-S and other power supply systems.
