Heschen DC Surge Protection Device for PV, WR-T2-DC, 2P 1000VDC 20kA, T2 Type, Flame Retardant, 35mm DIN Rail Mount, TUV CB Approved

WR-AC series Surge Protection Device (SPD) is appropriately used in IT, TT, TN-C, TN-S, TN-C-S, TN-C-S and low voltage power distribution systems, rated voltage up to 380V, to protect from direct and indirect lighting pulses and other transient surges. The SPD has two protection modes: MC and MD. SPD as a single side of the terminals, able to prevent any electrical contact, fixed mounted inside, limiting voltage. SPD has a built-in disconnector, when the SPD is invalid due to overheating or failure, the disconnector can automatically separate the SPD from the network, while sending an indication signal. The visible window shows the green color in normal operation, if it needs to be separated from the network, it will show the color red 1P+N, 2P+N, 3P+N SPD consist of 1P, 2P, 3P SPD and NPE neutral and grounding protection modules, used in TT, TN-S power system, etc. Secondary protection for the line.
