Heschen WR-T2-DC 3P 1500V DC 20KA Type T2 Fire Retardant DC Surge Protector 35mm DIN Rail Mounted TUV CB Certified

The WR-AC series surge protector (SPD) is suitably used in AC IT, TT, TN-C, TN-S, TN-C-S and low voltage power distribution systems, rated voltage up to 380V, to protect against direct and indirect lighting pulses and other transient surges. SPD has two protection modes: MC and MD. SPD as only one side of the terminals, can prevent electrical contact, fixed mounted indoors, limiting voltage. SPD is equipped with built-in disconnector, when the SPD is invalid due to overheating or failure, the disconnector can automatically separate the SPD from the network, meanwhile sending an indication signal. Visible window will show green color during normal service, if need to be separated from network, it will show red color SPD 1P+N, 2P+N, 3P+N composed of SPD 1P, 2P, 3P and NPE neutral and earth protection modules, used in the power supply system of TT, TN-S and so on. Secondary protection for in-line. Normal Green; Red Invalidation
