Product introduction

        TRS4 Series surge protective device(Abbreviation: SPD) are suitable for AC 50/60Hz, rated voltage up to 380V IT、TT. TN-C、TN-S、 TN-C-S and other power supply system, It protects the system from indirect and direct lightning effect or other transient over voltage.

        SPD is designed by according with GB 18802.1/IEC61643-1 standard.

Structure and Principle

      SPD as a port, its features are anti- shocking protection, indoor -mounted ins tlla tion, voltage limiting.

      SPD internal with a disconnector. When the SPD breakdown by over heating, the disconnector can remove from the power grid automatically, and show indication signal. When SPD is wor king normally, visible displays green, it disp lays red when it brea kdown.

      1P+N, 2P+N, 3P+N SPD accordingly consistof 1P, 2P,3P SPD+NPE zero ground protection module,applying toTN-S、TN-C-S and other power supply system.

Product Installation    

      With 35mm standard Din-rail moun ting, connecting copper stranded conductor is 2.5~35mm².

      Each pole is necessary with protection - -using fuse or miniature circuit breaker to protect. It helps to protect them in the short circuit when SPD brea kdown.

      SPD is installed in front of protected equipment and connected with power supply circuit. A class SPD is installed in the building home-entry line hold larger surge current total distribution box. B, C class products most install on the flo or distribution box, D class SPD is installed in front of equipment which with low surge current and in a low residualvoltage place.
