Thiết bị chống sét, Shanghai Leyun Surge Protector LYD1-C40 2P SPD 20KA-40KA

 Product overview
LYD1 series surge protector (hereinafter referred to as SPD) is suitable for AC 50/60Hz, rated voltage 380V IT, TT, TN-C, TN-S, TN-CS, and other power supply systems, for indirect lightning and direct lightning Impact or other transient overvoltage surge protection. Class I surge protector according to IEC61643-1:1998-02 standard. Class B surge protector. SPD has common mode (MC) and differential mode (MD) Protection mode. SPD complies with GB18802.1/IEC61643-1.
 Working principle
 SPD is a port, anti-shock protection, indoor fixed installation, voltage limiting type.
 The SPD has a built-in disconnector. When the SPD fails due to overheating or breakdown, the disconnector can automatically disconnect it from the grid and give an indication signal at the same time. The visible window is white when it is working normally, and it is red when it fails.
The maximum discharge current Imax of each line can reach 100kA.
 It is
installed at the junction of LPZ0A or LPZ0B area and LPZ1 area. It is installed on a standard guide rail of 35mm, and the connecting copper multi-strand flexible wire is 6~35mm2.
It is usually installed at the incoming low-voltage main distribution cabinet.
The grounding wire should be a yellow-green double-colored wire of more than 10mm ²  , and the length should not exceed 500mm.
In order to prevent the normal operation of the power grid after the failure of the surge protector, a fuse or circuit breaker should be connected in series with the protector connected to the L line (note: select according to the nominal current In).
